A horizontal bar chart compares the basic monthly cost of Netflix in seven countries, with country names on the y-axis and cost values on the x-axis. The visualization uses React state and effects to load CSV data via `d3.csv`, then renders SVG marks with `d3.scaleBand` and `d3.scaleLinear` for positioning. Axes are built manually from scales, drawing grid lines and tick labels with React elements. The code highlights integration of React’s `useState` and `useEffect` with D3 utilities for data-driven SVG rendering.
