This example visualizes the top 12 most-played Spotify songs using a horizontal bar chart, where each bar’s length encodes the song’s duration in milliseconds. The visualization loads data from a CSV file via `d3.csv`, then slices it to the first twelve rows before rendering with React and D3 v5. Axes are manually constructed using `scaleBand` for the categorical song names and `scaleLinear` for the numeric duration, with grid lines and tick labels drawn as SVG elements. The chart uses `useState` and `useEffect` for data fetching, and the final output is rendered as an SVG within a React component.
