{"version":"1.0","type":"rich","title":"Concept dependency graph (draft)","description":"This force-directed graph maps dependencies between data visualization concepts across ten chapters, with nodes colored by chapter and arranged along an axis that flows from foundational sources on the left to advanced topics on the right. A custom force within `d3.forceSimulation` pushes nodes horizontally based on their dependency-to-dependent ratio, while link distance and charge spacing separate connected ideas. Hovering reveals node descriptions, and the legend identifies chapter colors. The data loads from `nodes.json` and `edges.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b107d5c950564e01b509ed36e3903f43?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
