This pie chart visualizes the monthly price of HBOMAX subscriptions across different countries. A legend pairs each country with its corresponding cost in US dollars. The chart is built with D3 v5, using the `pie` and `arc` generators to create SVG paths and place text labels at each section's centroid. Data is loaded asynchronously from a CSV file via `d3.csv`, with colors assigned through `scaleOrdinal` and numeric values formatted with `d3.format`.
