This bubble chart shows the correlation between average horsepower, torque, and highway MPG for different car makes. Each circle’s position encodes horsepower and torque, its radius represents highway MPG, and its color distinguishes the make. The chart is created using D3 v7 with SVG rendering and transitions. It includes interactive tooltips on hover and legends for both bubble size and color categories. Data is loaded from a CSV file and visualized using `d3.scaleLinear`, `d3.axisBottom`, `d3.axisLeft`, and `d3.scaleOrdinal` for color mapping.
