This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes horsepower and torque on the x- and y-axes, while its radius and color represent highway MPG and the car make, respectively, with a color scale from `d3.interpolateTurbo`. Built with D3 v7, the SVG rendering includes interactive tooltips that display the make on hover, plus a legend for bubble size and color. Data is loaded from a CSV file, and the chart uses `d3.axisBottom` and `d3.axisLeft` for axes.
