This animated bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for 31 car makes. Each circle’s position encodes horsepower and torque, while its radius represents highway MPG and its fill color distinguishes the manufacturer. Built with D3 v7 (d3.csv, d3.scaleLinear, d3.scaleOrdinal, d3.axisBottom, d3.axisLeft), it includes interactive tooltips that display the make on hover. Data comes from the provided bubblechart.csv file.
