This visualization displays the top-selling books by population data from a CSV file, rendered as a horizontal bar chart. The code uses React hooks like `useState` and `useEffect` to load and manage data, while D3's `scaleBand`, `scaleLinear`, and `max` functions handle axes scaling and extents. SVG rectangles represent each book's population value, with axis ticks generated via `xScale.ticks()`. The example demonstrates a React-D3 integration pattern using d3.v5.
