This bubble chart visualizes the correlation between average horsepower and torque for various car makes, using bubble size to represent highway MPG and color to distinguish car brands. Built with D3.js (v7) and rendered as SVG, it reads data from a CSV file and features interactive tooltips that display the car’s make on mouseover. The visualization includes a legend for bubble size (MPG values) and a categorical color legend, with animated hover effects that adjust opacity and stroke width.
