This visualization displays the cost of basic Amazon Prime subscriptions across different countries, presenting a horizontal bar chart of the top twelve countries by price. The chart uses React for component management and D3 v5 for data binding, scaling, and layout, with SVG rendering. Data is loaded from a CSV file using D3’s `csv` function, and scales are created with `scaleBand` and `scaleLinear`. Grid lines and axis tick labels are manually generated by iterating over scale ticks, and each country is represented by a colored rectangle. The visualization updates reactively as data loads, initially showing a loading message.
