{"version":"1.0","type":"rich","title":"Untitled","description":"This example visualizes a hierarchical tree of COVID-19 data, showing confirmed cases, deaths, and recoveries across continents and countries. The tree layout uses d3.tree to position nodes, with SVG circles and text labels for each location. Hovering over a node triggers a tooltip displaying the specific statistics. The visualization uses d3.v5 and React, with an animated tree structure that renders the data in a clear, drill-down format.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/678f4a4b06b647718261816a574b2d9a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
