This interactive bubble chart displays the correlation between average horsepower, torque, and highway MPG across various car makes. Each circle's position represents horsepower and torque values, while its radius encodes highway MPG and color distinguishes vehicle manufacturers. The visualization uses D3 v7 to load CSV data, render SVG elements, and implement a hover tooltip showing the make. A legend communicates circle size values and color categories. The chart includes axis labels and a title, with data sourced from the included bubblechart.csv file.
