This example displays the pricing of Amazon Prime in various countries as a pie chart generated with D3.js. Each slice, colored using a categorical scale, represents a country’s subscription cost in dollars, with values labeled directly on the chart and in a legend. The visualization uses D3’s `pie`, `arc`, and `scaleOrdinal` functions to compute and render the arc segments, while the data is fetched from a remote CSV file. An interactive SVG canvas updates the chart to show total prices across all selected regions.
