This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle's horizontal position maps to horsepower, its vertical position to torque, and its radius to highway MPG, while its color identifies the manufacturer. The chart uses D3.js v7 with SVG rendering and includes animated transitions for tooltip display. It features a legend for MPG scaling and color-coded make identification. The data originates from a CSV file containing aggregated performance metrics for 31 automotive brands.
