{"version":"1.0","type":"rich","title":"activity7.1","description":"This example visualizes the distribution of weather conditions from a CSV dataset as a pie chart. It counts occurrences of each condition, then renders the chart using D3 v7's `d3.pie` and `d3.arc` APIs, with slices colored via `d3.scaleOrdinal` and `d3.schemeCategory10`. Labels display each condition near its slice, and a separate legend is built using `d3.select`. The SVG output is 600 by 600 pixels, with data loaded asynchronously via `d3.csv` from a GitHub Gist.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b57a60058a04007838ced8b6d6e45bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
