This interactive bubble chart visualizes the correlation between average horsepower (x-axis), torque (y-axis), and highway MPG (bubble size and color) for various car makes. Built with D3.js v7, the SVG renders scaled circles positioned on linear axes, with color assigned via an ordinal scale using the `d3.interpolateTurbo` function. A hovering tooltip reveals the car make, and a legend clarifies the MPG scale. Data comes from the `bubblechart.csv` file, presented with animation on hover transitions.
