This gallery example demonstrates a horizontal bar chart that visualizes population data for various countries. The chart uses D3's `scaleBand` and `scaleLinear` functions to map country names to the y-axis and population values to bar widths, rendering the results as SVG rectangles. The data is loaded asynchronously from a CSV file via `d3.csv` and managed through React's `useState` and `useEffect` hooks. The visualization leverages React's declarative component model alongside D3's scaling utilities to produce a clean, interactive-free static chart.
