This bubble chart shows the correlation between average horsepower (x-axis), torque (y-axis), and highway MPG (bubble size) for various car makes, with each bubble colored by brand. Built with D3 v7, it renders as an SVG with animated tooltips. The visualization uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color mapping, and `d3.interpolateTurbo` to generate the color palette. Data is loaded from a CSV file, and the chart includes a legend for MPG values and a color-coded list of makes.
