{"version":"1.0","type":"rich","title":"Assignment 2 Tree graph","description":"This example shows a hierarchical tree graph with a root node labeled \"Venkat\" and four child branches, each splitting into two leaf nodes. Circles sized by the node's numeric `value` property sit at each point, while link and node colors derive from the `level` and `type` fields in the data. Built with D3 v5, the code uses `d3.tree()` and `d3.hierarchy()` to compute the layout, then renders SVG paths for curved links and circles with text labels. Colors come directly from the inline JavaScript data object, which is embedded in the source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8ce1a4aa0b2d467e8e18cfc706ca549a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
