{"version":"1.0","type":"rich","title":"SDV Activity 7","description":"This example shows the top 10 countries by population in 2020 using a pie chart rendered as SVG. It loads data from a GitHub gist CSV file and calculates the total population to proportionally size each slice. The visualization uses D3 v5 APIs including `d3.pie`, `d3.arc`, `d3.scaleOrdinal`, and `d3.format` to compute arcs, assign section colors, and format labels. A legend with colored rectangles and country names accompanies the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b61076c333b460f85e7c6ab4fc19b8e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
