{"version":"1.0","type":"rich","title":"Grid of Circles","description":"A grid of 200 circles is drawn across a 960-by-500 canvas, with 20 columns and 10 rows. The circles are evenly spaced by mapping their index positions to normalized coordinates between 0 and 1. Each circle is rendered with a fixed radius of 20 pixels using the Canvas 2D API, specifically `beginPath`, `arc`, and `fill`. The example demonstrates nested `for` loops to generate a regular spatial pattern, with no data source beyond the procedural loop logic.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e2194a82efee45bf980d5a4d3a33453b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
