This area chart compares three car attributes—horsepower, torque, and highway MPG—across different car makes using overlapping filled paths. Built with D3 v7, the visualization loads CSV data via `d3.csv`, scales values with `scaleBand` and `scaleLinear`, and renders the three series using `d3.area` paths in steelblue, orange, and green. The SVG output includes rotated x-axis labels, a legend, and axis titles, with the data sourced from a raw GitHub CSV file.
