-
-## Tech Stack
-
-- **imgui_bundle**: User interface
-- **ModernGL**: OpenGL graphics rendering
-- **NetworkX**: Graph data structures and algorithms
-- **NumPy**: Numerical computations
-- **community**: Community detection
-
-## Usage
-
-1. **Launch the Program**:
-   ```bash
-   python -m pip install -r requirements.txt
-   python graph_visualizer.py
-   ```
-
-2. **Load Font**:
-   - Place the font file `font.ttf` in the `assets` directory
-   - Or modify the `CUSTOM_FONT` constant to use a different font file
-
-3. **Load Graph File**:
-   - Click the "Load GraphML" button in the interface
-   - Select a graph file in GraphML format
-
-4. **Interactive Controls**:
-   - **Camera Movement**:
-     - W: Move forward
-     - S: Move backward
-     - A: Move left
-     - D: Move right
-     - Q: Move up
-     - E: Move down
-   - **View Control**:
-     - Hold right mouse button and drag to rotate view
-   - **Node Interaction**:
-     - Hover mouse to highlight nodes
-     - Click to select nodes
-
-5. **Visualization Settings**:
-   - Adjustable via UI control panel:
-     - Layout type
-     - Node size
-     - Edge width
-     - Label visibility
-     - Label size
-     - Background color
-
-## Customization Options
-
-- **Node Scaling**: Adjust node size via `node_scale` parameter
-- **Edge Width**: Modify edge width using `edge_width` parameter
-- **Label Display**: Toggle label visibility with `show_labels`
-- **Label Size**: Adjust label size using `label_size`
-- **Label Color**: Set label color through `label_color`
-- **View Distance**: Control maximum label display distance with `label_culling_distance`
-
-## Performance Optimizations
-
-- Efficient graphics rendering using ModernGL
-- View distance culling for label display optimization
-- Community detection algorithms for optimized visualization of large-scale graphs
-
-## System Requirements
-
-- Python 3.10+
-- Graphics card with OpenGL 3.3+ support
-- Supported Operating Systems: Windows/Linux/MacOS
