This example visualizes the basic cost of Netflix subscriptions across 15 countries using a horizontal bar chart rendered with React and D3. It employs React hooks for state management and data fetching, with D3’s `csv` parser to load external data, `scaleBand` for categorical y-axis positioning, and `scaleLinear` for continuous x-axis scaling. The SVG bars and axes are generated manually through React components, while D3’s `max` and `format` functions handle data processing.
