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, while its size maps to highway MPG and its color distinguishes car brand. Built with D3 v7, the SVG rendering includes interactive tooltips that reveal the car make on hover. The chart incorporates a legend for bubble size and a color-coded categorical legend for each make, with all data loaded from a CSV file.
