This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes, with each bubble’s position on the x- and y-axes representing horsepower and torque, and its size mapping to MPG. The color of each bubble encodes the car make. Built with D3 v7, the visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color, and `d3.csv` to load data. Interactive tooltips appear on mouseover, showing the make. Animated transitions and a legend for size and colors are included.
