This example visualizes the monthly cost of business internet plans across 12 countries using a horizontal bar chart rendered as SVG. The chart uses D3’s `scaleBand` and `scaleLinear` for positioning and sizing bars, with React managing state and rendering. Data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV file, and the top 12 rows are selected. Axes are drawn manually with D3 ticks and gridlines, while the bars appear in blue without labels.
