This bar chart displays the gold medal counts for the top 10 countries from a CSV dataset of Olympic medal records. The visualization uses D3.js version 5 within a React application, employing `scaleBand` for the categorical country axis and `scaleLinear` for the numeric gold medal axis. The SVG output renders orange bars with green gridlines and axis labels. Data is loaded asynchronously using D3’s `csv` function, and React’s `useState` and `useEffect` hooks manage the data loading and rendering process.
