This bubble chart shows the relationship between average horsepower and torque across car makes, with bubble size encoding highway MPG. It is built with D3 v7, rendering SVG circles positioned by linear scales for the x- and y-axes. A color scale, using d3.interpolateTurbo, distinguishes car makes, and the chart includes a legend for highway MPG. Interactive tooltips appear on mouseover, displaying the make of each car. Data is loaded from a CSV file, and the visualization updates dynamically with hover effects.
