This visualization displays a heatmap of yearly infection counts for US states from 1970 to 1980. It uses p5.js to render colored squares on a 1000x1000 canvas, with darker reds indicating higher infection numbers. The map includes state labels, year markers, and a color legend. Hovering over any square triggers a tooltip that reveals the exact year, location, and infection count. The data is loaded from a CSV file via the `loadTable` function, with square fill colors computed directly from the numeric infection values.
