This example visualizes the basic monthly cost of Netflix in 15 countries using horizontal bar marks encoded by length. It renders SVG via React components and D3 scales, including `scaleBand` for country categories and `scaleLinear` for cost values. Data loads asynchronously from a CSV using `csv` from D3 v5, and the code manually constructs axes with grid lines and tick labels through JSX. The implementation demonstrates a hybrid approach, letting React manage the DOM while D3 handles data parsing, scaling, and axis generation.
