This bubble chart visualizes the relationship between power, torque, and fuel efficiency for various vehicles. Each bubble is positioned by its power and torque values, with the radius scaled to fuel efficiency and colors assigned per vehicle using d3.interpolateTurbo and d3.scaleOrdinal. Built with d3.v7, it renders via SVG with interactive tooltips showing vehicle make on mouse events. Axes are created using d3.axisBottom and d3.axisLeft, while a legend indicates fuel efficiency scaling. The data is loaded from a CSV file.
