This bubble chart displays the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position maps horsepower and torque, while its size encodes highway MPG and its color identifies the manufacturer. The visualization includes interactive tooltips showing the make on hover, as well as legends for bubble size and color. It uses D3 v7 to load CSV data, render SVG circles, axes, and scales, and relies on D3 event handlers for hover effects. Animated transitions are applied to the tooltip for smooth appear and fade behavior.
