This bubble chart shows the correlation between average horsepower (x-axis), average torque (y-axis), and highway MPG (bubble size and color) across 31 car makes. Each bubble represents a make, colored via a d3.scaleOrdinal with an interpolateTurbo palette derived from the dataset. The chart includes axes with labels, a legend for bubble size (Highway MPG) and color, and a hover tooltip displaying the make name. It is rendered as SVG using d3.csv for data loading, with animations on mouseover and mouseleave.
