This bubble chart visualizes Pokémon battle stats, plotting each creature’s Total stats on the x-axis and Attack on the y-axis, with bubble size encoding HP. The D3 v7 code uses `d3.scaleLinear`, `d3.scaleSqrt`, and `d3.scaleOrdinal` with `d3.schemeCategory10` to color points by Type_1. A legend maps fifteen Pokémon types, while axis labels and an SVG render from `data.csv` loaded via `d3.csv`.
