This bar chart visualizes car performance by comparing a categorical attribute against a numeric metric, displaying the top 20 values sorted in descending order. Using D3 v7, it loads CSV data from a GitHub gist, applies `d3.scaleBand` and `d3.scaleLinear` for positioning, and renders SVG rectangles with `d3.interpolateTurbo` coloring. Rotated axis labels and value annotations highlight each data point, while hover effects change bar fill color.
