{"version":"1.0","type":"rich","title":"D3 Matrix Example","description":"This force-directed network diagram displays relationships between four concepts—people, radiation, seeds, and cancer—with link opacity encoding connection strength. It is built with D3 v3’s `d3.layout.force` simulation and SVG rendering, with arrow markers on curved paths. Clicking a node enlarges its circle and changes its label color, while a double-click resets the size. The data is loaded from `data.json` via `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1d2bc1eb90a243759204af67318955c9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
