This example shows the Olympic medal count for the top 12 countries as a horizontal bar graph, with red gridlines along the x-axis and country labels on the y-axis. The visualization loads data from a CSV file and renders the bars as SVG rectangles sized by each country’s total medal count. Built with React and D3 v5, it uses `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and `csv` for data loading, with `select` and `axisLeft`/`axisBottom` available but not applied directly.
