Prompt for this run

Using the pre-provided d3.min.js (global d3), render an interactive force-directed graph of about 40 nodes in several clusters with draggable nodes, hover highlighting of neighbors, and zoom/pan. Define the sample nodes and links inline.

The user wants me to create a single-page web app (index.html) that uses d3.min.js (already in the current directory) to render an interactive force-directed graph. Let me plan the features:

1. ~40 nodes in several clusters (let's say 5 clusters with 8 nodes each)
2. Draggable nodes
3. Hover highlighting of neighbors (when hovering a node, highlight its direct neighbors, dim others)
4. Zoom/pan support
5. All inline - CSS in <style>, JS in <script>
6. Sample nodes and links defined inline
7. Uses d3 from the local d3.min.js file

Let me create a visually appealing force-directed graph with:
- Nodes colored by cluster
- Links between nodes (more links within clusters)
- Labels on nodes
- Hover effects that highlight neighbors and dim non-neighbors
- Drag behavior
- Zoom/pan behavior

I'll generate the nodes and links programmatically with some randomness but seeded for consistency.

→ write index.html (12895 bytes)

The file has been created. Let me verify it exists and check it looks right.

→ bash {"command":"ls -la index.html d3.min.js"}

Everything looks good. Both files are present. Let me summarize what I built.

Done! **`index.html`** is ready. Here's what's packed in: ### Features | Feature | Details | |---|---| | **40 nodes** | 5 clusters of 8, each representing a team (Engineering, Design, Marketing, Data Science, Operations) | | **~90+ links** | Dense intra-cluster connections (chain + random), sparse inter-cluster bridges | | **Drag** | Grab any node and reposition it; simulation reheats on drag | | **Hover highlight** | Hovering a node brightens it and its direct neighbors, dims everything else, and colors connected edges in the cluster's color | | **Tooltip** | Shows name, cluster, and connection count on hover | | **Zoom/Pan** | Scroll to zoom, drag background to pan, double-click to reset view | | **Glow effects** | SVG filter-based glow for a rich dark-theme look | | **Legend** | Live cluster legend with node/edge counts | | **Responsive** | Resizes and recenters on window resize | The graph uses a seeded random generator (`mulberry32(42)`) so the topology is reproducible across reloads. No network requests — everything is self-contained.
