This example visualizes the correlation between torque, horsepower, and highway MPG across various car makes using an animated bubble chart. Each circle represents a car make, positioned by horsepower (x-axis) and torque (y-axis), with circle size encoding highway MPG and color distinguishing makes. Built with D3 v7, the visualization includes interactive tooltips on mouseover, a size legend, and a color legend. It reads data from a CSV file and renders SVG elements with linear scales for axes, bubble sizing, and color interpolation.
