{"version":"1.0","type":"rich","title":"Collapsible Tree Final Version 2","description":"This interactive collapsible tree visualization displays a hierarchical structure of computer science topics using SVG and animation. Users can click on circular nodes to expand or collapse their children, while clicking on text labels opens a Wikipedia page for that topic. The tree uses D3 v4’s zoom behavior, transitions with `duration`, and a custom depth-based layout algorithm. Node positions are calculated using depth counts and a scale factor, with data sourced from the `newData2.js` file. The visualization includes white text outlines and color-coded nodes to indicate expandable branches.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4ac92be73c4944c19a633989378384dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
