This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes torque (y-axis) and horsepower (x-axis), while its radius scales with highway MPG and its color distinguishes the vehicle brand. Built with D3 v7, the SVG visualization includes hover tooltips that display the car make, plus a legend for MPG bubble sizes and color categories. Data is loaded from a CSV file using `d3.csv`, with scales created via `d3.scaleLinear` and `d3.scaleOrdinal` for mapping values.
