This heatmap visualization displays violent crime rates for US states from 2008 to 2019 using CORGIS data. It presents a grid of colored squares, with each square representing a state-year combination and color intensity mapping to the crime rate via red fill values. The visualization is built with p5.js, using its `loadTable` function to fetch and parse a remote CSV file. It dynamically draws the legend, axes, and state labels through the canvas API, with the color scale ranging from dark red for lower rates to bright red for higher ones.
