This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle’s position encodes horsepower and torque, while its radius and color represent highway MPG and car make, respectively. The view includes interactive tooltips on hover and a legend for both bubble size and color categories. Built with D3 v7, it uses SVG rendering, scaleLinear and scaleOrdinal for mapping, and data loaded via d3.csv.
