This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while its size represents highway MPG and its color distinguishes the car brand. The visualization uses D3 v7 with SVG, rendering static bubbles that reveal a tooltip showing the car make on hover. Data is loaded from a CSV file and styled via inline attributes and CSS.
