**Creating index.html** I need to create an index.html file that includes inline CSS and JavaScript. It’s essential to load the existing d3.min.js correctly by specifying the exact filename in the script source. I should double-check the files to ensure everything is in order. This way, I can make sure that my project setup is solid and functioning properly! It's always good to be thorough.

**Implementing seeded RNG and visualization** I'm thinking about how to quickly implement seeded random number generation (RNG). To do this effectively, I'll create a link array using explicit loops based on node IDs. I'll define cluster node arrays and generate links in line. I need to ensure performance for about 40 nodes, then write the file with CSS and JS. I also plan to use D3 for visualization, creating a zoomable SVG that I'll translate to keep the center focused. I’m checking if I need to handle resizing properly as well.**Setting up SVG with zoom and interactions** I'm laying out the steps for my SVG implementation with zoom functionality. I'll start by creating the zoom handler that updates the `gZoom` transform based on the event's transformation data. The initial transform will be set to identity, and I’ll center the `gRoot` group with a translate. Then, I'll add nodes to `gZoom`. When the resize event occurs, I’ll update the width and height, ensuring that the `gRoot` transform gets adjusted appropriately. For node interaction, I want to handle hover events to highlight nodes and display labels, starting with the text opacity set to zero unless active. Finally, I’ll write the necessary HTML and script files.

**Fixing CSS for nodes** I'm starting with some precomputed values for x and y, but I'm running into a collision issue with the d.id character code. I need to fix the CSS for the node dimensions, specifically adjusting the dim class opacity to 0.18 and handling the .node.active circle stroke and text opacity. However, the dim class doesn't reduce text visibility, though it does set pointer-events to none. I also need to ensure the link selection line class is highlighted correctly. Now, I'll respond to the user.
Created **`index.html`** with a self-contained D3 (global `d3`) **force-directed clustered graph** (~40 nodes) featuring: - **Several clusters** (inline-defined nodes/links) - **Draggable nodes** - **Hover highlight** of the hovered node’s **neighbors + incident edges** - **Zoom/pan** (mouse wheel / trackpad zoom, drag background to pan) File: `index.html` (in the current directory).
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 clusters renders nicely; drag and zoom/pan work, keyboard has no effect (expected).

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.
