This bubble chart displays the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle represents a make, positioned by its horsepower and torque, with size encoding highway MPG and color distinguishing brands. Hovering reveals the make name via a tooltip. Built with D3 v7, the SVG visualization uses `d3.scaleLinear` and `d3.scaleOrdinal`, and reads data from a CSV file.
