This bubble chart displays the correlation between average horsepower, torque, and highway MPG across multiple car makes. Each circle encodes horsepower on the x-axis, torque on the y-axis, and highway MPG through both bubble size and color via a turbo color scale. Hovering reveals a tooltip with the car make. The visualization uses D3 v7 with SVG, linear scales, ordinal color mapping, and a custom legend for bubble sizes and categories.
