This bubble chart displays the correlation between average horsepower (x-axis), average torque (y-axis), and highway MPG (bubble size) for various car makes. The color of each bubble represents the car manufacturer. The chart includes axes with labels, a legend for the bubble size scale indicating highway MPG values, and a color legend for the makes. Hovering over a bubble reveals a tooltip showing the car make. The visualization is built with D3.js (v7), using its scaling and selection APIs, and renders as an SVG with animated transitions for the tooltip's opacity.
