This pie chart visualizes the distribution of website traffic by source, with visitor counts in thousands. It fetches data from a CSV file hosted on GitHub and renders the chart using Chart.js on an HTML canvas element. The chart displays twelve labeled categories with distinct translucent colors and a legend positioned on the right side. The code retrieves the data asynchronously via the `fetch` API, parses the CSV rows, and configures the pie chart with responsive settings and a descriptive title.
