{"version":"1.0","type":"rich","title":"Infection Type Chart","description":"A stacked bar chart displays infection case counts across Chinese provinces, segmented by transmission type: Travel, Relative, Social, and Unknown. Users toggle between absolute counts and percentage-normalized views via radio buttons, triggering animated transitions. The visualization uses d3.layout.stack for stacking, d3.scale.ordinal for the x-axis, and SVG rectangles with smooth transitions. Data comes from data3.csv, sorted alphabetically by province, with a color-coded legend and hover tooltips for additional detail.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/147a0448e64144a19a0fee65f2fc0cfa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
