This example shows the basic cost of Netflix subscriptions across 15 countries using a horizontal bar chart. The visualization renders SVG marks and channels through a React component that combines `useState`, `useEffect`, and `useCallback` hooks with D3’s `csv`, `scaleBand`, and `scaleLinear`. Data is loaded from a remote CSV file, with axis ticks drawn manually via `xScale.ticks()`. React controls the component lifecycle, while D3 manages scales and layout calculations for the rectangular bars.
