This visualization uses a bubble chart to show the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each bubble’s position encodes horsepower and torque on the x and y axes, while its radius represents highway MPG via a linear scale. Color distinguishes makes using a ordinal scale with interpolated Turbo colors. The chart includes hover tooltips, a legend for MPG values, and static SVG rendering with D3 v7. Data comes from bubblechart.csv.
