This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position reflects horsepower and torque values, while its size corresponds to highway MPG, and color distinguishes the manufacturer. The D3.js (v7) visualization uses `d3.scaleLinear` for axes and bubble radius, with `d3.scaleOrdinal` for color mapping. Interactive tooltips appear on hover, and the chart includes legends for both bubble size and color categories. Data is loaded from a CSV file.
