{"version":"1.0","type":"rich","title":"Infection Type Chart","description":"This stacked bar chart displays COVID-19 infection cases across Chinese provinces, broken down by transmission type: public transit, relative, social, and unknown. The visualization uses d3.layout.stack to stack the data series, with d3.scale.ordinal for the x-axis and d3.scale.linear for the y-axis. A form allows switching between absolute case counts and percentage-normalized views via stack.offset(\"expand\"), with smooth transitions on the bars and axis. Hovering highlights individual segments using SVG opacity changes, and a custom legend is drawn manually.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12fac5b286324a3ba9b304f7e6ee6e4a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
