This animated bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for 31 car makes, with each circle’s position on the x- and y-axes encoding horsepower and torque, while its radius encodes highway MPG. Rendered as an SVG using D3 v7, the chart includes interactive tooltips on mouseover and a dual legend for bubble size and categorical color scale. Data is loaded from a CSV file via `d3.csv`, with scales defined using `d3.scaleLinear` and color assignment via `d3.scaleOrdinal` combined with `d3.interpolateTurbo`.
