This example shows the most streamed songs and their basic costs, with a horizontal bar chart rendered as SVG. It loads data from a CSV file using `d3.csv`, filters to the first 12 rows, and maps values with `scaleBand` for the y-axis and `scaleLinear` for the x-axis. The React component uses `useState` and `useEffect` to fetch and store data, while D3’s `axis` and formatting utilities are imported but not directly used; instead, ticks and grid lines are manually drawn. The chart is styled with red gridlines and no axis components.
