This bubble chart displays the relationship between average horsepower, average torque, and highway MPG for various car makes. Using D3.js version 7, the visualization maps horsepower to the x-axis and torque to the y-axis, with each make represented by a colored circle sized at a constant radius of 600 pixels. The code loads data from a CSV file and employs `d3.scaleLinear` for both axes, while `d3.scaleOrdinal` with `d3.schemeCategory10` assigns distinct categorical colors to differentiate car manufacturers.
