This visualization shows the correlation between average horsepower, torque, and highway MPG for various car makes. Each bubble represents a car brand, positioned by horsepower on the x-axis and torque on the y-axis, with bubble size encoding highway MPG, colored by make. The chart, rendered as an SVG using D3 v7, builds the visualization with `d3.scaleLinear` for axes and bubble sizing, `d3.scaleOrdinal` for colors, and includes an interactive tooltip on mouseover that displays precise values. Data comes from a CSV file containing averages for 30+ automotive manufacturers.
