This example shows the monthly cost of basic Amazon services across different countries, displayed as a horizontal bar chart. The visualization ranks twelve country codes by their associated costs, with a red gridline marking each value on the x-axis. The chart uses pre-loaded CSV data and renders in SVG via React. It implements D3 version 5’s `scaleBand` and `scaleLinear` to map country codes and cost values, while `csv` fetches the external dataset and `max` calculates the domain for the value axis.
