This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle's x-position represents horsepower, the y-position represents torque, and the circle's radius encodes highway MPG, with colors distinguishing different manufacturers. Hovering over a bubble reveals the car's make via a custom tooltip. The visualization uses D3.js v7 to render SVG graphics, with scales for x, y, and bubble size, and an ordinal color scale for the categorical data. A legend explains the bubble size mapping.
