This stacked bar chart displays the average horsepower, torque, and highway MPG for various car makes, sorted by total value. The chart uses a horizontal layout with segments colored in shades of orange to represent each specification. It is built with D3 v7 and renders as an SVG, employing `d3.stack()` for the stacked data transformation, `d3.scaleOrdinal` for color mapping, and `d3.axisBottom` and `d3.axisLeft` for axes. The data is loaded from a CSV file and processed with numeric conversion.
