A heatmap displays yearly case rates per 100,000 people, with a marker indicating when the measles vaccine was introduced in 1963. The visualization uses D3 v6 to create an SVG, employing scales like `d3.scaleLinear`, `d3.scaleBand`, and `d3.scaleSequentialSqrt` with the `d3.interpolatePuRd` color scheme. A line marks the vaccine introduction year, while the legend and tooltips clarify case counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/034a74ef8ede46459baf38d93025e3d1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
