This example displays a horizontal bar chart of the top 15 movies by their Metascore, using React to manage the component state and D3 version 5 for data processing and scales. It loads a CSV file from a GitHub Gist, parses the numeric score values, and renders the bars as SVG rectangles. The code uses `d3.csv`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.max` to handle data loading, axis positioning, and scaling, with React’s `useState` and `useEffect` to fetch and store the data before rendering.
