This pie chart visualizes the premium monthly cost of Netflix subscriptions across different countries, displaying the top 10 most expensive plans. The chart uses D3 v5’s `pie` and `arc` generators to create SVG segments, with `scaleOrdinal` and `schemeCategory10` for color mapping. Each slice’s fill color corresponds to the cost value, and a legend lists country names with their respective prices in US dollars. Data is loaded asynchronously from a CSV file hosted on GitHub Gist via `d3.csv`, and the render function sorts the data by premium cost before slicing the top ten entries.
