{"version":"1.0","type":"rich","title":"Untitled","description":"This interactive network diagram uses a force-directed layout to display a small hierarchical dataset from a JSON file. The visualization distinguishes node types by color: blue for collapsed packages, light blue for expanded ones, and orange for leaf nodes. Users can click any node to expand or collapse its children, triggering a re-layout. The code leverages the D3.js v3 layout APIs, specifically `d3.layout.force` for the simulation and `d3.layout.tree` to generate links. The force simulation is configured with custom `linkDistance`, `charge`, and `gravity` parameters, and the rendering is done as an SVG with click-to-toggle interaction.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2cf8bfe367cb4d8cab6550012b740dc2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
