This bubble chart displays the correlation between average horsepower, torque, and highway MPG across various car manufacturers. Each circle represents a make, positioned by horsepower (x-axis) and torque (y-axis), with the circle's radius encoding highway MPG and its color distinguishing the manufacturer. The visualization uses D3.js (v7) to render SVG elements and includes interactive tooltips on hover. A legend shows the mapping of circle size to MPG values. Data is loaded from a CSV file.
