This bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble’s x-position maps to horsepower, y-position to torque, and size to highway MPG, with colors assigned per make. Built with D3.js v7 as an animated SVG, the visualization reads data from a CSV file and includes interactive tooltips on hover. A legend displays both the bubble-size scale for MPG values and a color key for each car brand.
