Prompt for this run

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.

**Developing Interactive Graph**

I'm currently focused on integrating D3.js into a single `index.html` file to create an interactive force-directed graph. My aim is to render approximately 40 nodes organized into distinct clusters, ensuring each node is draggable for user interaction.

**Building HTML Structure**

I'm proceeding with the creation of `index.html`. My immediate focus is on defining the data generation logic, which involves setting up 40 nodes, each assigned a group ID of 0, 1, or 2, and then establishing links, primarily within clusters.

→ write index.html (7139 bytes)

**Building Interactive Graph**

I've successfully implemented the core features for the force-directed graph in `index.html`. This includes interactivity like draggable nodes, hover-based neighbor highlighting, and smooth zoom/pan functionality for 40 nodes organized into clusters.

**Confirming Local Dependencies**

I've verified that all scripts, including `d3.min.js`, are locally sourced. The data generation for nodes and links appears sound, creating the specified 40 nodes across 4 groups. Zoom functionality is standard D3.

→ bash {"command":"grep -o \"version\\\":\\\"[^\\\"]*\" d3.min.js | head -n 1"}

I have created a single-page web application in `index.html` that uses the local `d3.min.js` library to render an interactive force-directed graph. ### Features: - **Graph Data**: 40 nodes divided into 4 clusters (groups) with both intra-cluster and inter-cluster links. - **Force Simulation**: Includes charge (repulsion), link constraints, centering, and collision detection to prevent node overlap. - **Interactivity**: - **Draggable Nodes**: Click and drag nodes to reposition them; the simulation adjusts in real-time. - **Hover Highlighting**: Hovering over a node highlights its direct neighbors and connections while dimming the rest of the graph. A tooltip also appears with node details. - **Zoom & Pan**: Use the mouse wheel to zoom and click-drag on the background to pan. - **Styling**: A dark-themed, full-screen visualization with responsive resizing. The application is entirely self-contained within `index.html` and requires no external internet access. ```html  ```
