{"version":"1.0","type":"rich","title":"D3 v4 Circle-Packing","description":"This example shows a hierarchical circle-packing layout of the Flare software package’s class hierarchy, with each node’s size proportional to its value and color mapped to depth. Using D3 v4’s `d3.stratify` to build the hierarchy from CSV data and `d3.pack` for layout, circles are rendered as SVG groups. Interactivity highlights all ancestor circles on hover via the `d3.selectAll` and `classed` methods, while leaf labels are clipped to their circles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8cba87bbc4d1486d815429dade12d1f6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
