{"version":"1.0","type":"rich","title":"Hello VizHub","description":"This example demonstrates data cleaning of a CSV file containing survey responses about favorite days of the week. The code uses D3.js version 5’s `d3.csv` to fetch the external dataset from a VizHub URL, then applies a series of `Array.filter` calls to remove invalid entries such as empty strings, dates, and non-day answers. After cleaning, `Array.map` standardizes the responses by capitalizing the first letter of each day name. The processed data is logged to the browser console for inspection.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/414d6a1521e541a685ab724d13ab9bae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
