This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 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 car make, respectively. Built with D3 v7, the SVG visualization includes a tooltip on hover, a size legend for MPG values, and color-coded makes. Data is loaded from a local CSV file, with scales and axes created via `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`.
