Key Architectural Decisions

1. React Flow

2. Zustand

Why: Lightweight (<1KB), simple hook-based API, no boilerplate, ideal for graph state management

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

    • 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
