{"version":"1.0","type":"rich","title":"Tree","description":"A hierarchical tree diagram displays the structure of programming languages, grouped into Web, System, and Data categories. The visualization uses a static dataset defined in JavaScript. D3.js v7 with an SVG rendering approach draws the graph, employing `d3.hierarchy` and `d3.tree` to compute the layout. Nodes are represented as colored circles, color-coded by depth using `d3.scaleOrdinal` with `d3.schemeCategory10`, while links and text labels are appended via D3's data-join methods. The tree is oriented horizontally, placing parent-child connections left-to-right.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/55ca4190f48b4a0d8022c9ea1f0ec188?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
