This animated bubble chart explores the correlation between average horsepower, torque, and highway MPG across numerous car makes. Each circle’s horizontal position maps to horsepower, vertical position to torque, and its radius encodes highway MPG, with color distinguishing manufacturers. Built with D3 v7, the SVG visualization includes interactive tooltips that appear on mouseover using event-driven handlers, plus a legend for MPG scaling. Data is loaded from a CSV file, and the chart uses d3.scaleLinear and d3.scaleOrdinal for axis and color mapping.
