This bubble chart visualizes the correlation between average horsepower (x-axis), average torque (y-axis), and highway MPG (bubble size) for various vehicle types, with each bubble's color representing its manufacturer. The chart uses D3.js v7 with SVG rendering and includes interactivity through mouseover events that display a tooltip showing the vehicle's make. The visualization implements d3.scaleLinear for axes and bubble sizing, d3.scaleOrdinal for color assignment, and d3.interpolateTurbo for the color palette. A legend displays the mapping between bubble size and mileage values, while the data is loaded from a CSV file.
