This visualization displays a bubble chart that explores the correlation between average horsepower, torque, and highway MPG across various car makes. Each bubble represents a car brand, positioned by horsepower on the x-axis and torque on the y-axis, while the bubble size encodes highway MPG and color distinguishes between manufacturers. The chart includes interactive tooltips that appear on mouse hover. Built with D3 v7 and SVG, the code uses `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.interpolateTurbo` for color encoding, with data loaded from a CSV file.
