{"version":"1.0","type":"rich","title":"Courses Tree","description":"This interactive course tree visualizes a hierarchical math curriculum across five levels, using circles positioned by level and links to show prerequisites. Clicking a course highlights all related prerequisite connections in red and adds the course label to a fixed sidebar, while clicking again removes it. Built with D3 v5, it uses the `linkVertical` generator to draw curved paths and `d3.json` to load the node/edge data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/db5e7d3ca937420cae97d5910c11df1d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
