{"version":"1.0","type":"rich","title":"Assignment_2","description":"This example presents two synchronized views of historical population data for multiple countries: a stacked area chart and a pie chart. The area chart uses `d3.stack()` and `d3.area()` to show population changes across eight census years, while the pie chart uses `d3.pie()` and `d3.arc()` to display the 2022 population distribution. Both visualizations load data from a CSV file via `d3.csv`, employ `d3.scaleOrdinal` with `d3.schemeCategory10` for coloring, and render as SVG. Numeric population values are displayed directly on the area chart layers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/941c1458b58c40b783bd872e9af15f1f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
