This bubble chart shows the correlation between average horsepower, torque, and highway MPG across 31 car makes. Each circle represents a make, positioned by horsepower on the x-axis and torque on the y-axis, with circle size scaled to highway MPG and color mapped by make. The visualization, rendered in SVG, uses d3.scaleLinear for axes and bubble size, d3.scaleOrdinal with interpolateTurbo for colors, and interactive tooltips on mouseover. A legend displays both the MPG size scale and color-coded make categories.
