{"version":"1.0","type":"rich","title":"task1.2","description":"A radial tree visualization displays a hierarchical structure of topics and keywords associated with the restaurant \"Mon Ami Gabi,\" with \"Positive Topics\" branching into multiple \"topic\" nodes and their corresponding leaf terms. The SVG rendering, built with D3 v4, uses `d3.cluster` to position nodes in a circular layout, with text labels scaled by depth and rotated for readability. Panning and zooming are implemented via D3's `d3.zoom` behavior, while curved links connect parent and child nodes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/070cde0eb4dc4f698eaec14a1cc6a455?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
