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.

I need to create a single-page web app in index.html that uses d3.min.js (already present in the directory) to render an interactive force-directed graph. The requirements are: 1. About 40 nodes in several clusters 2. Draggable nodes 3. Hover highlighting of neighbors 4. Zoom/pan functionality 5. Sample nodes and links defined inline 6. No external resources - everything in one self-contained file Let me first check what's in the current directory and verify d3.min.js exists.

Good, d3.min.js is present. Now I'll create the index.html file with an interactive force-directed graph using d3.

I notice there's an issue with my d3.forceCluster custom force - it's not properly calling the initialize method. Let me fix that and also ensure the links stroke function works correctly. The forceCluster function needs to be properly initialized. Let me fix these issues.
The file is complete. I notice there's an issue with the custom `forceCluster` implementation - it needs to properly initialize. Let me fix that:

I made an error with the edit syntax. Let me fix it - I need to include the nodes variable declaration in the forceCluster function.

The edit tool is having issues. Let me try using write to completely rewrite the file with the corrected code.
Let me rewrite the file with the corrected cluster force:
/workspace/index.html (12719 bytes)Successfully wrote 12719 bytes to /workspace/index.html
thinking
The file has been written. Let me verify it's correct and check the node count.
{"command":"cat /workspace/index.html | grep -c \"id: \\`${clusters\""}/bin/bash: -c: line 1: unexpected EOF while looking for matching `"' Command exited with code 2
thinking
Let me just check the node count differently.
{"command":"grep -c \"nodes.push\" /workspace/index.html"}1
thinking
Let me verify the node count is correct by checking the loop structure.
{"command":"grep -A2 \"for (let i = 0; i < nodeCount\" /workspace/index.html"}for (let i = 0; i < nodeCount; i++) { nodes.push({ id: `${cluster}-${i}`,
thinking
The file looks correct. Let me verify the total number of nodes generated by looking at the logic. Each cluster generates 10-12 nodes (random), and there are 4 clusters, so we'd get 40-48 nodes. Let me also verify the file is self-contained and has no external dependencies.
{"command":"grep -E \"(src=|href=|url\\()\" /workspace/index.html | head -10"}<script src="d3.min.js"></script>
thinking
Good - only d3.min.js is loaded as a script. Let me verify the file is complete and the node count is correct.
The index.html file is complete. Let me verify the node count:
{"command":"grep -c \"nodes.push\" /workspace/index.html && wc -l /workspace/index.html"}1 385 /workspace/index.html
thinking
The count shows 1 because `nodes.push` is inside a loop. Let me verify the logic is correct by checking the structure more carefully.

The file is complete and looks good. Let me verify it runs properly by checking the structure once more. The file has: 1. ✅ d3.min.js loaded as a script tag 2. ✅ CSS in <style> tag 3. ✅ JS in <script> tag 4. ✅ No external resources/CDNs 5. ✅ ~40 nodes (4 clusters × 10-12 nodes each = 40-48 nodes) 6. ✅ Draggable nodes (d3.drag()) 7. ✅ Hover highlighting of neighbors 8. ✅ Zoom/pan (d3.zoom()) 9. ✅ Clusters with different colors The file is ready. Let me verify the total node count by examining the code logic - each cluster generates 10-12 nodes, and we have 4 clusters, so that's 40-48 nodes total.
The `index.html` file is complete. It contains: - **Self-contained**: All CSS in `<style>` tag, all JS in `<script>` tag - **Uses local d3.min.js**: Loaded via `<script src="d3.min.js"></script>` - **~40 nodes in 4 clusters**: Each cluster has 10-12 nodes (Analytics, Infrastructure, Frontend, Backend) - **Interactive features**: - Draggable nodes with physics-based repulsion - Hover highlighting of neighbor nodes and connecting links - Zoom/pan via mouse wheel and drag - Tooltip showing node info on hover - Cluster labels in center positions - **Visual styling**: Dark gradient background, colored nodes per cluster, clean labels

EVALUATION
Force-directed clustered graph with drag/zoom/pan working; keyboard inputs unsupported (expected) leaving zoomed frontend view.

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.
