This bubble chart shows the correlation between average horsepower, torque, and highway MPG for 31 car makes. Each circle’s position encodes horsepower on the x-axis and torque on the y-axis, while its radius and color represent highway MPG. The visualization uses d3.csv to load data, d3.scaleLinear for axes and bubble size, and d3.scaleOrdinal with interpolateTurbo for color mapping. Interactive tooltips appear on mouseover. A legend explains the MPG size scale, and a second legend lists makes with their colors.
