This bubble chart shows the correlation between average horsepower, torque, and highway MPG across various car makes, using bubble size to encode MPG and color to distinguish makes. Built with D3 v7, the visualization uses `scaleLinear` for the x/y axes and bubble radius, `scaleOrdinal` for color mapping, and `interpolateTurbo` to generate a color palette. It reads from a local CSV file, renders as SVG, and includes interactive tooltips on mouseover, plus a legend showing the MPG-to-radius scale.
