This scatter plot visualization shows the correlation between average horsepower, torque, and highway MPG across different car makes, with each bubble representing a make and its size encoding the highway MPG value. The chart uses D3.js v7 to render an SVG with linear scales for the x and y axes, a third scale for bubble radius, and an ordinal color scale with interpolated turbo colors to distinguish makes. Interactive tooltips display the make name on hover, while a legend explains both the bubble size encoding and the color categories.
