Let me check the current directory and the d3.min.js file.

Let me build the force-directed graph app. I'll create a self-contained index.html.

Wait, I added a `cluster` force using forceManyBody with negative strength which is redundant with charge. But it's fine, it just adds repulsion. Actually that plus the x/y soft forces should work. Let me verify the file exists.

Let me verify the node count: 40 members are pushed in a loop so one push call. Links = 32 intra (8 per cluster, 7 extra each = 35... wait). Each cluster has 8 members, hub + 7 others = 7 intra links per cluster × 5 = 35. Plus 18 bridges = 53 links. Good. Let me do a quick sanity check the file loads without errors by checking the JS is well-formed. I can extract the script and run a syntax check roughly. Actually the script uses browser globals. Let me just parse it with node using a check that strips nothing. Actually node can't parse because d3 etc. but syntax check via new Function works for syntax only. Let me verify.
{"command":"cd /workspace && node -e \"\nconst s=require('fs').readFileSync('index.html','utf8');\nconst m=s.match(/<script>([\\s\\S]*?)<\\/inline JS syntax OK
Done. I built a self-contained single-file app at `/workspace/index.html` (using the pre-provided `d3.min.js`). **What it does:** - **~40 nodes in 5 themed clusters** (Core, Data, Web, Systems, AI), each rendered with a node-size based on importance, colored per cluster, with labels. - **Inline sample data** — star-shaped intra-cluster links (each member links to its cluster hub) plus 18 cross-cluster bridge links (~53 links total). - **Force simulation** (`forceSimulation`) combining link, charge, center, and soft per-cluster `forceX`/`forceY` pulls so the clusters separate into a radial arrangement. - **Draggable nodes** — drag pins the node (`fx`/`fy`), bumps alpha, and keeps neighbors highlighted while dragging. - **Hover highlighting** — hovering a node dims everything else and brightens the node + its incident links/neighbors (with CSS transitions). - **Zoom & pan** — D3 zoom with scale extent 0.3–5 applied to a container `<g>`, driven by scroll/wheel and drag; double-click zoom disabled so plain panning feels natural. - **Polish** — glow filter on nodes, legend/HUD with live counts, resize handling, and dark glassmorphic UI. The graph SVG scales to the full viewport, edge labels follow the cluster layout, and everything runs 100% offline with no external resources.

EVALUATION
Force-directed clustered graph renders nicely; drag pans/zooms view, wheel zooms out, clusters colored distinctly.

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.
