This pie chart displays the cost of Amazon Prime subscriptions across different countries. The visualization uses D3 v5 APIs including `d3.csv`, `d3.pie`, `d3.arc`, and `d3.scaleOrdinal`. The data is fetched from a remote CSV file containing country and price information. Revenue values are shown as black text labels on each pie slice, while a legend to the right maps a country to its corresponding price, with slices colored using a predefined array of ten colors. The pie is rendered using SVG elements appended to a 960x500 canvas.
