This example shows the basic cost of Netflix subscriptions across ten countries, sorted descending and displayed as a pie chart with a color-coded legend and cost labels. Built with D3 v5 and React, it uses `d3.pie`, `d3.arc`, and `scaleOrdinal` with `schemeCategory10` to generate SVG paths. Data is loaded via `d3.csv` from a GitHub gist, and mouseover events log the selected value to the console.
