This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for 31 car makes. The x-axis maps horsepower, the y-axis maps torque, while bubble size encodes highway MPG and color distinguishes car makes. Built with D3 v7, the SVG includes axes, a legend for MPG values, and an interactive tooltip displaying make on hover. Data is loaded from a CSV file using `d3.csv`. The chart relies on `d3.scaleLinear` for positional and size scales, and `d3.scaleOrdinal` with `d3.interpolateTurbo` for color assignment.
