T4
This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle's x-position represents horsepower, y-position represents torque, and size encodes MPG, with color differentiating car manufacturers. Data is loaded from a CSV file. The chart utilizes D3 v7's `scaleLinear`, `axisBottom`, `axisLeft`, `scaleOrdinal`, and `interpolateTurbo` APIs. Interactive tooltips display the car make on mouseover, and a legend explains the bubble sizing and color scheme.
