This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle's x-position maps to horsepower, y-position to torque, and its size encodes highway MPG, with a color scale distinguishing car brands. Built with D3.js v7, the visualization reads CSV data and renders as an SVG. Interactive tooltips display the car make on hover, while a legend explains the bubble size scale.
