This bubble chart shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle’s position encodes the first two variables, while its size represents highway MPG and its color denotes the car manufacturer. Built with D3 v7, the visualization reads data from a CSV file and renders circles as SVG elements. Interactive tooltips appear on mouseover, and a legend displays both the bubble-size scale and color-coded makes.
