{"version":"1.0","type":"rich","title":"Q2-1-ASSIGN-8","description":"This example displays a hierarchical tree of movie genres, from major categories like Action and Drama down to specific films such as Star Wars and Parasite. Each node is drawn as a colored circle with a text label, using a vertical layout with straight links. Built with D3 v7, it applies `d3.stratify` to construct the hierarchy from flat parent-child data and `d3.tree` to compute node positions, rendering the SVG output with unique colors from `d3.scaleOrdinal` and a custom legend.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e048c74eec1e4610a036f88819c1faf5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
