{"version":"1.0","type":"rich","title":"Activity7","description":"This example displays the top 30 countries by population from a CSV dataset, rendering each country’s 2020 population as a numeric value. It loads D3 v5 via UNPKG and uses the `csv` function to fetch and parse the remote data, converting population values to numbers. The React-based `useData` hook manages asynchronous data loading with `useState` and `useEffect`, while `d3.select` updates a message div with a greeting. The visualization demonstrates ES6 module imports and simple DOM manipulation through D3.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/072219e685674100a0c231f677a19f12?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
