{"version":"1.0","type":"rich","title":"RT15_Tree structure","description":"A hierarchical tree chart visualizes the structure of COVID-19, its variants, symptoms, and associated medications. The interactive SVG animation, rendered with D3.js, displays a root square node for COVID-19, branching into circular nodes for variants like Alpha and Delta, each with prevalence percentages and linked medications, then cascading to symptom sub-nodes with their own frequency percentages. The visualization uses D3's force simulation to dynamically position the tree nodes, with custom colors and node types distinguishing different data levels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/090fbb601f5d4617b3f91ff5e20f3ae9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
