### 3. Vite
**Why**: Lightning-fast HMR, modern ES modules, optimized builds, superior developer experience

### 4. Tailwind CSS
**Why**: Rapid development, consistent design system, small production bundle, easy responsive design

### 5. TypeScript (Strict Mode)
**Why**: Type safety for complex graph structures, better IDE support, catch errors at compile time

## What Works in This Initial Version

   - Each type has distinct colors
   - Nodes appear at random positions

3. **Create Relations/Edges**
   - Drag from any node handle
   - Connect to another node's handle
   - Edges automatically created with default type
   - Visual feedback during connection

4. **Edit Graph**
   - Drag nodes to reposition
   - Delete nodes (selects and press Delete/Backspace)
   - Delete edges (select and press Delete/Backspace)
   - Clear entire graph with button

5. **Visual Customization**
   - Nodes display type badges with colors
   - Nodes show labels
   - Edges have type-based styling (solid, dashed, dotted)
   - Selected elements highlighted

6. **Responsive Layout**
   - Header with project title
   - Toolbar with controls
   - Full-screen graph editor
   - Tailwind responsive classes

## Testing the Application

### Basic Workflow Test
1. Start dev server: `npm run dev`
