This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG across various car makes using a CSV dataset. It employs D3 v7 to render SVG circles scaled by highway MPG, colored by car make, and positioned along linear axes for horsepower and torque. Interactive tooltips display each make on hover, while a legend indicates bubble size and color categories. The chart also demonstrates loading D3 via UNPKG and using a local ES6 module.
