This example visualizes the basic cost of Netflix subscriptions across ten countries using a pie chart, with each slice colored via `d3.scaleOrdinal` and `d3.schemeCategory10`. A legend lists country names and their costs in dollars, formatted with a custom number formatter. The visualization uses `d3.pie` and `d3.arc` to generate SVG paths, and data is loaded asynchronously from a CSV file via `d3.csv`, then sorted and sliced to show the top ten values.
