This bar chart shows the monthly basic cost of Amazon services across twelve countries, with countries listed vertically and costs plotted horizontally on a red-tinted grid. The visualization loads CSV data from a GitHub gist using D3’s `csv` method and React hooks (`useState`, `useEffect`) to fetch and store the dataset. D3 scales (`scaleBand` and `scaleLinear`) position the bars, while SVG rectangles and manually rendered tick labels—instead of D3 axes—draw the chart. The React app renders the final SVG, with the data truncated to the first twelve rows for display.
