This heat map visualizes the average attack values of Pokémon across seven types—Bug, Dark, Fire, Grass, Ground, Normal, and Water—for six generations, using a purple sequential color scale from light to dark to indicate increasing attack ranges. Each type is displayed as a row of colored squares, with one square per generation, alongside a legend showing six bins (0–20, 20–40, up to 100+). The visualization loads CSV data from GitHub using p5.js’s `loadTable`, then renders the grid and labels with the Canvas API and `rect` and `text` functions in `draw()`.
