{"version":"1.0","type":"rich","title":"Activity-7.1","description":"This example displays a pie chart showing the distribution of university tuition fees by country, with the title \"University Tuition Distribution by Country\". It loads data from a CSV file using `d3.csv`, then uses `d3.rollup` to compute the mean tuition fee per country. The chart is rendered as an SVG using D3’s `pie`, `arc`, and `scaleOrdinal` APIs, while a legend lists each country with its corresponding color and average fee. The code also demonstrates ES6 module import with `myMessage.js`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a776c19a62804d5d804eac6a466d8da8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
