{"version":"1.0","type":"rich","title":"Activity_9-pie chart","description":"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()`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c0e96ab3ca1b48778f66ec3d75faad4d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
