{"version":"1.0","type":"rich","title":"Arc and path lab","description":"The Arc and path lab demonstrates a circular visualization of hierarchical data, where topics and sub-topics are positioned in a radial layout. It uses D3 v6 to render SVG shapes, including arcs generated with `d3.arc` and circles appended directly. The data is loaded from an embedded JSON file containing topic hierarchies with associated metadata like size and sentiment. The visualization adapts to the screen width, centering its elements within a responsive SVG container, and applies basic styling for orange-filled shapes and white text labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d49df51da0f945b0a9b728f73ef061bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
