This bubble chart visualizes the correlation between average horsepower, torque, and highway MPG for various car makes. Each circle's position is mapped to horsepower (x-axis) and torque (y-axis), while its size represents highway MPG and its color identifies the car brand. Built with D3 v7, the SVG rendering includes interactive tooltips that display the make on mouseover. The chart uses `d3.scaleLinear` for axes and bubble size, `d3.scaleOrdinal` for color mapping, and `d3.interpolateTurbo` for the color palette, with data loaded from a CSV file.
