This interactive bubble chart visualizes the correlation between average horsepower (x-axis), average torque (y-axis), and highway MPG (bubble size) for various car makes. Using D3.js v7, it renders SVG circles with color-coded makes and provides tooltips on hover showing the make name. The visualization includes axis labels, a legend for the MPG bubble size scale, and a categorical color legend. Data is loaded from a CSV file and rendered with SVG primitives, with transitions used for tooltip opacity.
