This animated bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes. The position of each bubble encodes horsepower (x-axis) and torque (y-axis), while its size represents highway MPG and its color indicates the car make. Built with d3.v7 and rendered as SVG, the chart includes interactive tooltips that appear on mouseover, revealing the car make. A legend shows circle sizes for MPG values and color-coded dots for each make, with data loaded from a local CSV file.
