{"version":"1.0","type":"rich","title":"task1.1","description":"This radial tree visualization displays a hierarchical topic structure, with the root \"Topics\" branching into four main topics, each containing fifteen associated terms. The D3 v4 code uses `d3.cluster()` to compute the layout and projects nodes onto a circular coordinate system. Text labels rotate based on their angular position, while depth-dependent font sizes and edge curvature distinguish hierarchy levels. The SVG rendering includes pan and zoom functionality via `d3.zoom()`, applied to a background rectangle that captures pointer events.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4e8ecb5eb8214cde89975ee4ed0ae716?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
