This bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower on the x-axis and torque on the y-axis, while its radius represents highway MPG and its color distinguishes the manufacturer. The visualization uses D3 v7 with SVG rendering, including tooltips on mouseover and a custom legend for bubble size. It reads data from a CSV file and employs simple d3.scaleLinear scales for positioning and sizing.
