This example visualizes the users of OTT platforms as a horizontal bar chart, with each bar’s length encoding the population value. The code uses React’s `useState` and `useEffect` hooks to load CSV data via `d3.csv`, then renders SVG marks using JSX. D3 scales (`scaleBand`, `scaleLinear`) position the bars, while `xScale.ticks()` generates grid lines and tick labels. The data is sourced from a GitHub gist and limited to the first twelve rows.
