+  <h1>Grapher</h1>
+  <p><em>An interactive mathematical expression plotter for BoredOS, supporting both 2D and 3D visualizations.</em></p>
+</div>
+
+---
+
+Grapher is a built-in GUI application that lets you type any mathematical equation and see it plotted in real time. It supports 2D explicit and implicit curves as well as full 3D surface visualization — including both explicit surfaces (`z = f(x, y)`) and implicit surfaces (`f(x, y, z) = c`).
+
+> [!NOTE]
+> Grapher is located at `src/userland/gui/grapher.c`. It runs as a standard BoredOS GUI process and can be launched from the terminal or from the dock.
+
+---
+
+## Features at a Glance
+
+| Feature | Details |
+|---|---|
+| **2D Explicit** | Plot `y = f(x)` curves |
+| **2D Implicit** | Plot any `f(x, y) = g(x, y)` contour via marching squares |
+| **3D Explicit** | Plot `z = f(x, y)` surfaces |
+| **3D Implicit** | Plot any `f(x, y, z) = c` surface  |
+| **Rendering modes** | Wireframe and filled polygon modes |
+| **Height coloring** | Surfaces are colored by a blue→green→yellow→red gradient based on Z height |
+| **Phong-style shading** | Filled mode computes per-face normals and applies diffuse + ambient lighting |
+| **Parallel rendering** | Evaluation and projection are distributed across 4 worker threads via `sys_parallel_run` |
+| **Preset equations** | 7 built-in presets accessible from the toolbar |
+| **Auto-fit** | 2D view auto-fits the Y axis to the plotted curve on first plot |
+| **Atomic Color-Depth Buffer** | All 3D drawing uses a 64-bit atomic buffer to prevent depth/color race conditions |
+
+---

+## Writing Equations
+
+Grapher parses equations entered as plain text. It supports a subset of mathematical notation with automatic implicit multiplication.
+
+### Supported Functions
+
+| Syntax | Meaning |
+|---|---|
+| `sin(x)` | Sine |
+| `cos(x)` | Cosine |
+| `tan(x)` | Tangent |
+| `sqrt(x)` | Square root |
+| `abs(x)` | Absolute value |
+| `log(x)` | Natural logarithm (base *e*) |
+
+### Supported Operators
+
+| Operator | Meaning |
+|---|---|
+| `+` `-` `*` `/` | Arithmetic |
+| `^` | Exponentiation (right-associative) |
+| `(` `)` | Grouping |
+
+### Special Values
+
+| Token | Value |
+|---|---|
+| `pi` or `PI` | π ≈ 3.14159… |
+
+### Implicit Multiplication
+
+Adjacent tokens that would normally require a `*` are multiplied automatically:
+
+```
+2x        → 2 * x
+3sin(x)   → 3 * sin(x)
+(x+1)(x)  → (x+1) * x
+```
+
+### How Equations Are Classified
+
+Grapher looks at which variables appear in your equation to automatically choose the rendering mode:
+
+| Equation form | Auto-detected as |
+|---|---|
+| `y = f(x)` or just `f(x)` | 2D explicit |
+| `f(x, y) = g(x, y)` | 2D implicit |
+| `z = f(x, y)` | 3D explicit |
+| `f(x, y, z) = c` | 3D implicit |
+
+If you omit the `=` sign, Grapher treats the input as `y = <expression>` when no `y` or `z` is present, or as `<expression> = 0` otherwise.
+
+---
+
+## Example Equations
+
+### 2D Examples
+
+```
+y = sin(x)
+y = x^2
+y = cos(x)*x
+y = abs(x) - 2
+x^2 + y^2 = 25          ← circle (implicit)
+y = log(x)
+```
+
+### 3D Explicit Examples
+
+```
+z = sin(x)*cos(y)
+z = x^2 - y^2           ← saddle surface
+z = sqrt(25 - x^2 - y^2)
+```
+
+### 3D Implicit Examples
+
+```
+x^2 + y^2 + z^2 = 25    ← sphere
+x^2 + y^2 = 16          ← cylinder
+x^2 + y^2 - z^2 = 1     ← hyperboloid
+```

+|---|---|
+| **Scroll up** | Zoom in |
+| **Scroll down** | Zoom out |
+| **Ctrl+R** | Reset to default view (`x: [-10, 10]`) |
+
+### 3D Mode

+
+## Architecture Overview
+
+Grapher is implemented as a single self-contained C file. Below is a high-level breakdown of its major components:
+
+### Math Library
+
+Grapher uses the BoredOS freestanding **`libc/math.h`** library, which provides all the math functions it needs without depending on a host standard library:
+
+| Function | Description |
+|---|---|
+| `sin`, `cos`, `tan` | Trigonometry via Taylor series (8 terms, range-reduced to `[-π, π]`) |
+| `sqrt` | Newton-Raphson iteration (25 steps) |
+| `log` | Natural logarithm via Padé-style series |
+| `log2`, `log10` | Derived from `log` |
+| `exp` | Range-reduced Taylor series for `e^x` |
+| `pow` | Integer exponents use fast binary exponentiation; fractional exponents use `exp(e * log(b))` |
+| `fabs`, `fmod` | Absolute value and floating-point remainder |
+| `floor`, `ceil` | Rounding |
+| `sinh`, `cosh`, `tanh` | Hyperbolic functions |
+| `hypot`, `fmin`, `fmax`, `fclamp` | Utility helpers |
+
+The constants `M_PI`, `M_E`, `M_LN2`, `M_SQRT2` are also defined in the header.
+
+This library is automatically linked into every userland ELF — any app can `#include "math.h"` to use it.
+
+### Expression Parser
+
+Equations are parsed in three stages:
+
+1. **Tokenizer** (`tokenize`) — converts the input string into a flat token array. Handles implicit multiplication by inserting `*` tokens where needed.
+2. **Recursive Descent Parser** (`parse_expr`, `parse_term`, `parse_power`, `parse_unary`, `parse_atom`) — produces an Abstract Syntax Tree (AST) with up to `MAX_NODES = 128` nodes.
+3. **Bytecode Compiler** (`compile_ast`) — walks the AST in post-order and emits a flat instruction sequence for a simple stack machine. This avoids recursive evaluation during rendering hot paths.
+
+The resulting bytecode is then executed by `run_bc` for every sample point.
+
+### Rendering Pipeline
+
+#### 2D Rendering
+
+- **Explicit** — evaluates `y = f(x)` at every pixel column and connects adjacent samples with Bresenham lines.
+- **Implicit** — applies **marching squares** on a 200×130 grid to find sign changes in `f(x,y) - g(x,y)` and plots intersection pixels.
+
+#### 3D Rendering
+
+The 3D pipeline uses a multi-pass system parallelized across worker threads:
+
+| Pass | Function | Description |
+|---|---|---|
+| 1 | **Evaluation** | Samples the surface at grid points. For implicit surfaces, this uses **tri-axis marching**. |
+| 2 | **Projection** | Projects 3D world coordinates to 2D screen coordinates with perspective. |
+| 3 | **Drawing** | Rasterizes wireframe lines or filled triangles with Z-buffering. |
+
+##### Tri-Axis Marching (Implicit Surfaces)
+
+Unlike explicit surfaces that only need one evaluation per grid point, implicit surfaces require finding roots of $f(x, y, z) = 0$. To ensure complete surface connectivity and eliminate "cracks," Grapher marches along all three primary axes:
+
+1.  **X-Axis Pass**: For every $(y, z)$ pair, march along $x$.
+2.  **Y-Axis Pass**: For every $(x, z)$ pair, march along $y$.
+3.  **Z-Axis Pass**: For every $(x, y)$ pair, march along $z$.
+
+Each pass uses a multi-stage root finder (170 linear steps followed by 15 bisection iterations). By sampling along all three axes, the engine "catches" surfaces that are nearly parallel to any specific marching direction, ensuring that vertical walls and steep gradients are rendered solidly from any viewing angle.
+
+##### Atomic Color-Depth Buffer
+
+To prevent "z-fighting" and race conditions between parallel threads, Grapher uses a 64-bit atomic buffer (`graph_czb`). Each 64-bit word stores:
+-   **Upper 32 bits**: Z-depth (integer).
+-   **Lower 32 bits**: Pixel color (0xAARRGGBB).
+
+A single `__atomic_compare_exchange_n` operation ensures that a pixel's color and depth are updated together only if the new depth is closer to the camera than the existing one.
+
+Surface normals are estimated using central finite differences of the implicit function.
+
+#### Filled Mod
+
+When filled mode is active, each quad cell is split into two triangles. The average surface normal across the four corner vertices is computed and fed into `apply_shading`, which calculates:
+
+```
+intensity = ambient(0.3) + diffuse(0.7) * dot(normal, light_direction)
+```
+
+The light direction is fixed at `(0.577, 0.707, 0.408)` (normalized diagonal).
+
+#### Z-Buffer
+
+The depth buffer (`graph_zb`) stores integer depth values. `gfb_pixel_z` uses a **compare-and-swap (CAS) loop** via `__atomic_compare_exchange_n` so multiple parallel draw threads cannot produce race conditions.
+
+### Coordinate Systems
+
+#### 2D
+
+World coordinates map linearly to screen pixels:
+
+```c
+screen_x = (wx - view_x_min) / (view_x_max - view_x_min) * graph_w
+screen_y = (view_y_max - wy) / (view_y_max - view_y_min) * graph_h
+```
+
+#### 3D
+
+Points are first rotated by two Euler angles (`rot_y`, `rot_x`) then projected with a simple perspective divide:
+
+```
+persp = d / (pz + d)     // d = range_3d * 5
+sx    = px * scale * persp + screen_cx
+sy    = -py * scale * persp + screen_cy
+```
+
+---
+
+## Configuration Constants
+
+These can be changed at the top of `grapher.c` to tune behaviour:
+
+| Constant | Default | Effect |
+|---|---|---|
+| `ROTATE` | `1` | Set to `0` to disable auto-rotation in 3D mode |
+| `GRID_3D` | `41` | Grid resolution for 3D sampling. Higher = more detail, much slower |
+
+> [!WARNING]
+> Setting `GRID_3D` too high (e.g. 9000) will exhaust available memory. The `surf` grid and `surf_x`/`surf_y_3d` arrays are statically allocated at compile time: memory usage grows as **O(GRID_3D²)**. Values above ~512 are not recommended.
+
+> [!TIP]
+> `GRID_3D = 256` gives a good balance of detail and performance on typical BoredOS hardware emulation.
+
+---
+
+## Color Palette
+
+
+3D surfaces are colored by height using a 4-stop rainbow ramp:
+
+```
+Low  →  Blue → Cyan → Green → Yellow → Red  →  High
+```
+
+---
+
+## Preset Equations
+
+The built-in presets are shown in the dropdown when you click **Presets**:
+
+| Label | Type |
+|---|---|
+| `y = sin(x)` | 2D explicit |
+| `y = x^2` | 2D explicit |
+| `y = cos(x)*x` | 2D explicit |
+| `z = sin(x)*cos(y)` | 3D explicit |
+| `z = x^2 - y^2` | 3D explicit |
+| `x^2+y^2+z^2=25` | 3D implicit (sphere) |
+| `x^2+y^2=16` | 3D implicit (cylinder) |
+
+---
+
+## Known Limitations
+
+- **No parameter slider** — equations are static; there is no way to animate a parameter.
+- **No multiple equations** — only one equation can be graphed at a time.
+- **Implicit surface precision** — extremely thin or high-frequency implicit surfaces may still have small artifacts if the grid resolution (`GRID_3D`) is too low.
+- **3D implicit performance** — tri-axis marching evaluates the function significantly more times than explicit rendering; high resolutions will impact frame rate.
+- **Integer axis labels only for large values** — very large axis values are capped at `>2G` or `<-2G` due to `itoa` limitations.

+
+The Widget library (`libwidget.h`) provides a set of reusable UI components built on top of `libui.h`. It uses an abstract `widget_context_t` to decouple component logic from specific drawing implementations, making it easier to build complex graphical interfaces.
+
+## Widget Context
+
+To use any widget, you must first define a `widget_context_t`. This structure contains function pointers for basic drawing operations (rects, strings) and theme preferences.
+
+```c
+typedef struct {
+    void *user_data;
+    void (*draw_rect)(void *user_data, int x, int y, int w, int h, uint32_t color);

+## Button (`widget_button_t`)
+
+Standard interactive button with hover and click states.
+
+*   `void widget_button_init(widget_button_t *btn, int x, int y, int w, int h, const char *text);`
+*   `void widget_button_draw(widget_context_t *ctx, widget_button_t *btn);`
+*   `bool widget_button_handle_mouse(widget_button_t *btn, int mx, int my, bool mouse_down, bool mouse_clicked, void *user_data);`

+
+## Scrollbar (`widget_scrollbar_t`)
+
+Vertical scrollbar supporting dragging and track-paging.
+
+*   `void widget_scrollbar_init(widget_scrollbar_t *sb, int x, int y, int w, int h);`
+*   `void widget_scrollbar_update(widget_scrollbar_t *sb, int content_height, int scroll_y);`
+*   `void widget_scrollbar_draw(widget_context_t *ctx, widget_scrollbar_t *sb);`
+*   `bool widget_scrollbar_handle_mouse(widget_scrollbar_t *sb, int mx, int my, bool mouse_down, void *user_data);`
+
+> [!NOTE]
+> The scrollbar automatically calculates the "thumb" size based on the ratio of `h` to `content_height`.

+
+## TextBox (`widget_textbox_t`)
+
+Editable text field with focus support and keyboard handling.

+*   `void widget_textbox_init(widget_textbox_t *tb, int x, int y, int w, int h, char *buffer, int max_len);`
+*   `void widget_textbox_draw(widget_context_t *ctx, widget_textbox_t *tb);`
+*   `bool widget_textbox_handle_mouse(widget_textbox_t *tb, int mx, int my, bool mouse_clicked, void *user_data);`
+*   `bool widget_textbox_handle_key(widget_textbox_t *tb, char c, void *user_data);`
+
+---
+
+## Dropdown (`widget_dropdown_t`)
+
+Selection menu for picking one item from a list.
+
+*   `void widget_dropdown_init(widget_dropdown_t *dd, int x, int y, int w, int h, const char **items, int count);`
+*   `void widget_dropdown_draw(widget_context_t *ctx, widget_dropdown_t *dd);`
+*   `bool widget_dropdown_handle_mouse(widget_dropdown_t *dd, int mx, int my, bool mouse_clicked, void *user_data);`
+
+---
+
+## Checkbox / Radio (`widget_checkbox_t`)
+
+Toggleable options with support for circular "Radio" style or square "Checkbox" style.
+
+*   `void widget_checkbox_init(widget_checkbox_t *cb, int x, int y, int w, int h, const char *text, bool is_radio);`
+*   `void widget_checkbox_draw(widget_context_t *ctx, widget_checkbox_t *cb);`
+*   `bool widget_checkbox_handle_mouse(widget_checkbox_t *cb, int mx, int my, bool mouse_clicked, void *user_data);`
+
+---
+
+## Event Integration
+
+Widgets are designed to be polled within your `libui` event loop. Most handle-mouse functions return `true` if the event was "consumed" by the widget, allowing you to stop further processing for that event.
+
+```c
+if (ui_get_event(win, &ev)) {
+    bool handled = false;
+    handled |= widget_button_handle_mouse(&btn, ev.arg1, ev.arg2, is_down, is_clicked, NULL);
+    if (!handled) {
+        // Handle global window events...
+    }
+}

@@ -30,7 +30,7 @@ BoredOS supports two main types of storage for its FAT32 implementation:
    -   **GPT is NOT supported**: Currently, only **MBR (Master Boot Record)** partition tables or **raw (partitionless)** disks are supported.
    -   **Filesystem**: The partition must be formatted as **FAT32**.

-### 🔍 Auto-detection
+### Auto-detection
 The `Disk Manager` automatically probes primary and secondary IDE channels during initialization. If a valid FAT32 partition is found (either directly at sector 0 or via an MBR partition table), the disk is assigned a drive letter (starting from `B:`) and becomes accessible to the VFS.

 -   **User Space**: Userland applications are loaded into lower virtual addresses.
 -   **Page Faults**: The `mem/` subsystem registers an Interrupt Service Routine (ISR) for page faults (Interrupt 14). If a process accesses unmapped memory, the handler determines whether to allocate a new frame or terminate the process.

-## 🏗️ Kernel Heap
+## Kernel Heap

 Dynamic allocation within the kernel (`kmalloc` and `kfree`) is layered on top of the physical allocator. The kernel maintains its own heap area in virtual memory. When the heap requires more space, it requests physical frames from the PMM and maps them into the kernel's virtual address space.

 1.  **Limine Framebuffer**: During boot, the Limine bootloader requests a graphical framebuffer from the hardware (e.g., GOP in UEFI environments) and passes a pointer to this linear memory buffer to the kernel.
 2.  **Double Buffering**: To prevent screen tearing, the WM does not draw directly to the screen. It allocates a "back buffer" in kernel memory equal to the size of the screen. All drawing operations (lines, rectangles, windows) happen on this back buffer.
