This visualization shows the correlation between average horsepower, torque, and highway MPG across car makes using a bubble chart. Each bubble’s position encodes horsepower and torque, while its size reflects highway MPG and color distinguishes the make. The chart includes hover tooltips and legends for size and color. It is built with D3 v5, using scales for axes, bubble size, and ordinal color mapping, with SVG rendering and interactive mouse event handlers.
