This bubble chart explores the correlation between a vehicle's torque, horsepower, and highway MPG. The chart uses `d3.scaleLinear` for the x and y axes and for bubble radius, with a `d3.scaleOrdinal` for color-coding by car make. Interactive tooltips appear on mouseover, implemented with D3's selection and event handling. A legend for the bubble size scale is also included. The visualization is rendered as an SVG and uses D3's `d3.csv` to load data from a local file.
