{"version":"1.0","type":"rich","title":"activity7.1-QUESTION1","description":"This chart displays tourism revenue in billions of dollars for different destination countries as a pie chart with a custom legend. Each slice is colored using a pastel ordinal scale via `d3.scaleOrdinal`, sized by `d3.pie`, and drawn with `d3.arc`. Revenue values are labeled atop each slice. The chart reads CSV data from a GitHub gist and aggregates it with `d3.rollup` and `d3.sum`, rendering as SVG within an HTML page styled by CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/113e8a19e54a4333880a898a867c60c0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
