This example presents a bar chart of Netflix basic subscription costs across countries, using a horizontal layout with sorted data from a CSV file. The visualization renders SVG marks with React managing state and D3 handling scales and axes. D3’s `scaleBand` and `scaleLinear` position bars, while `axisBottom` and `axisLeft` generate tick marks. The code manually draws gridlines and labels, and fetches data via `d3.csv`. React’s `useState` and `useEffect` load and store the dataset, with `ReactDOM.render` mounting the interactive component.
