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 interactive force-directed graph using D3.js. Let me build a complete index.html file with: 1. ~40 nodes in several clusters 2. Draggable nodes 3. Hover highlighting of neighbors 4. Zoom/pan 5. Inline sample data (nodes and links) 6. d3.min.js loaded from local file Let me first check if d3.min.js exists in the current directory.
Let me check the environment first.

Good, d3.min.js is present. Now I need to create an index.html file with: 1. A force-directed graph with ~40 nodes in several clusters 2. Draggable nodes 3. Hover highlighting of neighbors 4. Zoom/pan 5. Inline sample data 6. d3.min.js loaded locally Let me design this carefully: - Create 40 nodes divided into 4 clusters (10 each) - Links within clusters (dense) and some inter-cluster links (sparse) - Force simulation with charge, link distance, center force - Drag behavior - Hover: highlight the hovered node and its neighbors, dim others - Zoom/pan with d3.zoom Let me write this all in one self-contained HTML file.
Good, `d3.min.js` is present. I'll create the interactive force-directed graph now

The file has been written. Let me verify it's correct and complete by reading it back, and also check that d3.min.js is present.
The file is written. Let me verify it's well-formed and the environment is correct.

The file is complete and well-formed. Let me verify the key features are all present: 1. ✅ ~40 nodes (40 nodes, 4 clusters of 10 each) 2. ✅ Several clusters (Alpha, Beta, Gamma, Delta) 3. ✅ Draggable nodes (d3.drag() implementation) 4. ✅ Hover highlighting of neighbors (mouseenter/mouseleave with adjacency map) 5. ✅ Zoom/pan (d3.zoom() with scaleExtent) 6. ✅ Inline sample nodes and links 7. ✅ d3.min.js loaded locally with `<script src="d3.min.js"></script>` 8. ✅ Single self-contained file (index.html) 9. ✅ No external resources or CDN requests 10. ✅ CSS in <style> tag, JS in <script> tag Everything looks good. Let me also do a quick sanity check on the HTML structure.
Everything checks out. The file is 363 lines, `d3.min.js` is present (274KB), and the HTML is well-formed. Here's a summary of what's in the app: **`/tmp/ws/index.html`** — a single self-contained page featuring: | Feature | Implementation | |---|---| | **40 nodes** in 4 clusters (Alpha, Beta, Gamma, Delta — 10 each) | Inline data array with `id`, `name`, `cluster` | | **Links** — dense intra-cluster + sparse inter-cluster bridges | Generated procedurally with `Math.random()` thresholds | | **Force simulation** | `d3.forceSimulation` with link, charge, center, collision, and position forces | | **Draggable nodes** | `d3.drag()` — fixes `fx`/`fy` during drag, releases on end | | **Hover neighbor highlighting** | Adjacency map built from links; hovered node + neighbors stay bright, everything else dims | | **Zoom & pan** | `d3.zoom()` on the SVG with scale limits `[0.15, 6]`, applied to a `<g>` wrapper | | **Tooltip** | Follows cursor on hover, shows node name, cluster, and connection count | | **Legend** | Fixed top-left panel with cluster color dots and node/link counts | | **Responsive** | Resizes on window resize, re-centers the simulation | | **Dark theme** | Slate-900 background with cluster-colored nodes and subtle styling | No external resources — everything is inline and the local `d3.min.js` is loaded via `<script src="d3.min.js">`.
TAKE IT TO CODE
A single self-contained HTML file — copy it and open in any browser, or reuse the prompt with your own pi-agent run.
RUN
EVALUATION
Force-directed clustered graph with legend, zoom/pan and drag work well; keyboard input not applicable, no self-animation drift.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
