This bubble chart shows the correlation between average horsepower and torque for different car makes, with bubble size encoding highway MPG and color distinguishing manufacturers. The visualization uses d3.csv to load the data, d3.scaleLinear for positioning and sizing, and d3.scaleOrdinal with d3.interpolateTurbo for color assignment. Interactive tooltips appear on mouseover, and SVG circles render the data with animated hover effects via CSS transitions.
