This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. The plot positions each vehicle make by its horsepower on the x-axis and torque on the y-axis, while the size of each circle encodes the highway MPG value, and the color distinguishes the car brand. The visualization uses d3.scaleLinear for axes and bubble sizing, d3.scaleOrdinal for color mapping with interpolateTurbo, and d3.select for SVG rendering. It includes interactive tooltips on mouseover and a legend for bubble size and color categories, sourced from a local CSV file.
