This visualization displays the basic cost of Netflix in 15 different countries using a horizontal bar chart rendered as SVG. The application uses React to manage state and render the chart, while D3 v5 handles data loading via `d3.csv`, scaling with `d3.scaleBand` and `d3.scaleLinear`, and margin calculations. The data is fetched from a GitHub-hosted CSV file, and the bars are drawn as `<rect>` elements positioned and sized using the D3 scales.
