This pie chart displays the distribution of website traffic by source, with each slice sized according to the number of visitors and a legend positioned on the right. It loads data from a CSV file using `d3.csv` from the D3 v7 library, then renders the chart on a Canvas element via the external Chart.js library, not through D3’s own rendering APIs. The chart uses a predefined color palette for the slices and includes a title indicating traffic values are in thousands.
