This bubble chart visualizes the correlation between average torque, horsepower, and highway MPG for various car makes. Each circle’s position encodes horsepower (x-axis) and torque (y-axis), while its size maps to highway MPG and its color represents the car brand. Built with D3 v7, the visualization renders as static SVG with interactive tooltips that display the make on hover. It includes size and color legends, and uses ordinal color scaling with `d3.interpolateTurbo`, with data loaded from a local CSV file.
