This visualization is an animated bubble chart that explores the relationship between average horsepower, torque, and highway MPG across different car makes. Each circle represents a car brand, with its horizontal position mapping to horsepower, vertical position to torque, and size encoding highway MPG. Color further distinguishes the makes. The chart uses D3.js v7 with the `d3.scaleLinear` and `d3.scaleOrdinal` APIs, rendered as an SVG. Interactive tooltips, implemented via `d3.select`, appear on mouseover. A legend uses sized circles to communicate the MPG scale.
