{"version":"1.0","type":"rich","title":"state averages","description":"This example presents four JavaScript practice problems that compute the average population of a small hardcoded array of U.S. states. The visualization shows no graphical output; instead, it demonstrates different programming approaches to calculating a mean. The code first uses the d3.mean() function from d3.v4, then replicates the calculation using a for loop, a forEach method, and a while loop, with results printed to the browser’s developer console. The data source is a literal states array containing names, IDs, and populations for Alaska, Virginia, Arizona, and Florida.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-cb091fb5d82ab640736f8b5520c1624e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
