This bubble chart shows the correlation between average horsepower, torque, and highway MPG across different car makes, with each circle sized by its highway MPG value and colored by make. Hovering reveals the make name via a tooltip. Built with D3 v7, it reads from a CSV file and renders interactive SVG circles with linear scales for position and size, plus an ordinal color scale for categorical make labels. A legend displays the MPG bubble sizes and make colors.
