This bubble chart shows the relationship between average horsepower, torque, and highway miles-per-gallon for various car makes. Horsepower is plotted on the x-axis, torque on the y-axis, and the bubble’s radius encodes highway MPG, with a color scale distinguishing different manufacturers. The visualization uses D3.js v7 to render an SVG with animated tooltips that display the car make on hover. A legend explains the MPG bubble sizes, and a color-coded list identifies each make. The chart is built from the `bubblechart.csv` dataset, with axes labeled and a turbo color interpolation applied to the categorical color mapping.
