This example displays a pie chart with a legend, using a dataset fetched from a GitHub-hosted CSV. Each sector of the pie represents a percentage value, and the legend lists the sector names alongside their corresponding percentages. The visualization is built with D3 v6, employing the `d3.pie` and `d3.arc` APIs for the chart itself, while the legend is constructed as a separate SVG element. Data is loaded asynchronously via `d3.csv`, and colors are assigned using a Tableau10 color scheme.
