This bubble chart visualizes the relationship between average horsepower, torque, and highway MPG for various car makes, using circle size to encode MPG and color to distinguish makes. Built with D3 v7, it renders as an SVG with animated dots that respond to mouseover events, displaying a tooltip with the car make. The chart includes a legend for MPG values and color-coded make categories, reading data from a CSV file and using scales such as `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` for color, and `d3.interpolateTurbo` for the color palette.
