{"version":"1.0","type":"rich","title":"Infection Type Chart","description":"This example shows the number of COVID-19 infection cases across Chinese provinces, stacked by transmission type (PublicTransit, Relative, Social, Unknown). Users can toggle between absolute counts and percentage-based views. The visualization uses d3.layout.stack and d3.svg.axis to render animated, stacked bar charts in SVG. A radio button triggers transitions between count and percent modes, while a custom tooltip and legend provide context. Data comes from a CSV file listing cases per province and transmission category.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a5d60be5c5b41bc9f368846629ec3f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
