No external resources except the pre-pro...The task is to create a single self-contained index.html file that uses the provided d3.min.js to render an interactive force-directed graph with about 40 nodes in several clusters. Nodes should be draggable, show hover highlighting of neighbors, and have zoom/pan support. I need to define sample nodes and links inline.
- HTML structure: <html>, <head>, <body>
- Include <script src="d3.min.js"></script>
- <style> for CSS
- Body with SVG element
- <script> for JS logic
For the graph:
- Use D3's forceSimulation with 4 forces: link, charge, center, and drag.
- Nodes: ~40, grouped into 4 clusters (10 nodes each).
- Links: intra-cluster dense connections, some inter-cluster bridges.
- Visuals: Different colors per cluster, node radius ~8-10, link width ~1 1.5, dark background.
- Interactivity:
- Draggable nodes: Use d3.drag on nodes, tie to simulation.
- Hover: Mouseover on node highlights it and neighbors (dim others, highlight connected).
- Zoom/pan: d3.zoom on SVG container.
- Data - Generate nodes inline with group id 1-4.
- Links: Generate intra-cluster (random density ~0.4), add ~10-20 inter links.
- Use SVG with viewBox for sizing, g container for zoom transform.
- Adjacency list for quick neighbor lookup.
- Tooltip via SVG <title> or simple div.
- Opacity fade for non-highlighted on hover.
- Initial positions clustered by group for better visual separation.
Code structure:
- Define width, height.
- Generate nodes, links arrays.
- Build adjacency map (id -> set of neighbor ids).
- Create SVG, container g.
- Apply zoom.
- Create simulation, forces.
- Bind links (lines), nodes (circles).
- Add drag behavior.
- Add mouseover/mouseout for highlight/reset.
- Start simulation.
CSS: body margin0, bg #111, svg 100% height, nodes stroke white, links gray.
Confidence: 70 (standard D3 force graph, but cluster positioning and exact link gen may vary slightly in impl).

thinking
The task is complete. The index.html file has been created with a self-contained interactive force-directed graph using D3.js. It includes:
The single-file web app has been built and written to **index.html**. Open it in a browser to interact with the force-directed graph (drag nodes, hover for neighbor highlights, zoom/pan with mouse wheel or drag).
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 graph with 4 colored clusters, physics settle over time, drag/wheel zoom work, but keyboard has no effect (as expected).

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.
