This horizontal bar chart visualizes the basic monthly cost of Netflix subscriptions across fifteen countries, using data loaded from a CSV file. The visualization integrates React for component management and D3 v5 for scales and SVG rendering, with `scaleBand` and `scaleLinear` mapping countries to bars and costs to widths. React state and hooks (`useState`, `useEffect`) manage the asynchronous data loading, while custom React elements render axis ticks and rectangles directly, avoiding D3’s selection methods.
