This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG across car makes. Each circle represents a make, positioned by horsepower on the x-axis and torque on the y-axis while its radius encodes highway MPG. Colors distinguish manufacturers, with a size legend and black tooltips on hover. Built with D3 v7, the SVG renders static circles using scaleLinear for axes and size, scaleOrdinal for color, and event listeners for interactive tooltips.
