This example displays country-wise basic internet costs as a horizontal bar chart, loading data from a CSV file and rendering it as SVG marks. The React component uses state and effects to fetch and parse the data, while D3’s `scaleBand` and `scaleLinear` map country names and cost values to pixel positions. Axes are manually constructed using array mappings for ticks and labels, with rectangle elements representing each bar. The visualization integrates React’s declarative rendering with D3’s scaling utilities, demonstrating a hybrid React-and-D3 approach for static chart generation.
