This interactive bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble’s position reflects its horsepower (x-axis) and torque (y-axis), while its size encodes highway MPG, and its color distinguishes the car brand. The visualization uses D3.js v7 with SVG rendering, implementing tooltips on mouseover and a legend for MPG values. Data is loaded from a CSV file and processed with d3.csv, while scales and axes are built using d3.scaleLinear and d3.axisBottom/Left.
