This example visualizes the basic cost of Netflix subscriptions by country, using a pie chart to show the proportional contributions of each nation. The chart is rendered as an SVG using D3.js (v5) within a React framework, with slices colored via a categorical color scale. Data is loaded from a CSV file hosted on GitHub, and the chart displays the top ten countries by contribution, with a legend listing each country and its corresponding cost in dollars. Mouseover events log the contribution value to the console.
