{"version":"1.0","type":"rich","title":"Billy's circle","description":"A single gray circle sits at a fixed position on an empty SVG canvas. The visualization demonstrates basic SVG shape creation with D3.js, using `d3.select` to append a circle element with explicit radius, x-coordinate, and y-coordinate attributes. The rendering relies on D3 v4's SVG manipulation API, with the circle drawn at coordinates (89, 74) and a radius of 22 pixels on a 960 by 500 viewport. No data source or interactive behavior is present; the example simply shows static geometric output.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-191048e034edad42ba58ea4d9323b3f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
