Interactive Org Chart Prompts

Create an interactive org chart component for my app. I want users to see a hierarchy where they can click to expand and collapse branches.

Framework: [React, Vue, vanilla JS, etc.]
Library preference: [D3.js, React Flow, GoJS, or suggest one]

Requirements:
1. Display hierarchical data as connected boxes
2. Click a node to show/hide its children
3. Visual lines connecting parent to children
4. Start with top levels expanded, deeper levels collapsed

My data looks like this:
[paste your data structure, e.g., { id, name, title, children: [] }]

Keep it simple. I want to understand the basic pattern first. Show me:
- The component code
- How to pass in my data
- How to style the nodes (basic CSS)

I'm learning, so explain each part simply.

Add zoom and pan controls to my org chart so users can navigate large hierarchies.

Framework: [React, Vue, vanilla JS, etc.]
Current code: [paste your existing org chart code or describe it]

Requirements:
1. Zoom in/out buttons (or pinch-to-zoom on mobile)
2. Pan by dragging the background (not nodes)
3. "Fit to screen" button to reset view
4. Smooth animations when zooming
5. Show current zoom level (optional)

Also handle:
- Minimum and maximum zoom limits (don't zoom to infinity!)
- Mobile touch gestures
- Keyboard shortcuts (+ and - keys)

Keep the code simple. I want to understand how zoom/pan works with my existing chart.

Add drag-and-drop functionality to my org chart so users can reorganize the hierarchy.

Framework: [React, Vue, vanilla JS, etc.]
Current code: [paste your existing org chart code or describe it]

Requirements:
1. Drag any node to move it
2. Drop on another node to make it a child of that node
3. Visual feedback while dragging (ghost image, drop zones)
4. Update the underlying data when reorganization completes
5. Undo button to revert last change

Also consider:
- Can any node be moved, or only certain ones?
- What happens if you drag a parent onto its own child? (prevent cycles)
- Save changes to backend? (show where to add API call)

Keep it beginner-friendly. I want to understand the drag-and-drop pattern.

Transform my org chart into a mind map layout where the central idea branches out in all directions.

Framework: [React, Vue, vanilla JS, etc.]
Current code: [paste your existing org chart code or describe it]

Requirements:
1. Central node in the middle of the screen
2. Child nodes branch outward (not just downward like a tree)
3. Automatic layout so nodes don't overlap
4. Curved connecting lines for a natural look
5. Click to expand branches in any direction

Also want:
- Different colors for different branch depths
- Ability to add new nodes by clicking "+" buttons
- Auto-save as users add ideas

This is for a brainstorming app where users build ideas visually.
