This pie chart visualizes Canadian immigrant data from 2013, showing the proportion of immigrants from each continent. The chart uses D3.js v6 to create an SVG pie layout with `d3.pie()` and `d3.arc()`, coloring each slice with a hue based on its index. Hovering over a slice displays a tooltip with the continent’s percentage of the total, calculated via `d3.sum()`. A legend accompanies the chart, listing each continent and its exact immigrant value. The data loads from a remote CSV file via `d3.csv()`.
