{"version":"1.0","type":"rich","title":"average questions","description":"This example presents four JavaScript practice problems embedded in an HTML page, focused on calculating the average population of a small array of U.S. states. It first uses `d3.mean()` with an accessor function, then demonstrates manual computation via a `for` loop, a `forEach` method, and a while loop. The code outputs results to the browser’s developer console rather than rendering any visualization, making it a purely logic-based exercise using D3 v4’s array utilities and core JavaScript iteration patterns.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-cfb897da28a19456bae8085b39f19913?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
