{"version":"1.0","type":"rich","title":"Wiki","description":"This visualization displays a hierarchical tree of Russian Wikipedia science categories, using node color to encode a numerical group value from the dataset. The D3 v5 code applies a tree layout with horizontal links, scaling node positions via the `x` and `y` accessors, and renders circles and text labels in SVG. A linear color scale maps the group values from white to purple, while zooming is enabled through `d3.zoom()`. A legend shows the mapping for the two extreme group values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a6244cdbfb4345eeb861c885840713a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
