This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes, using D3.js v7 with SVG and animation. Each circle’s horizontal position maps to horsepower, vertical position to torque, and radius to highway MPG, while color encodes the vehicle make via an ordinal scale with interpolated Turbo colors. The chart includes an interactive tooltip that displays the make on hover, and a legend explains the bubble-size scale. Data is loaded from a CSV file, with axes, labels, and styling built using D3’s scaleLinear, axisBottom, and axisLeft methods.
