This bubble chart displays the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s horizontal position represents horsepower, the vertical axis shows torque, and bubble size encodes highway MPG, while color distinguishes vehicle manufacturers. The visualization uses D3.js v7 with SVG rendering and animation. It reads data from a CSV file, employs `d3.scaleOrdinal` and `d3.interpolateTurbo` for coloring, and includes interactive tooltips on mouseover along with a legend for bubble size and categorical color mapping.
