{"version":"1.0","type":"rich","title":"Concentric circles chart using SVGt","description":"A concentric circles chart displays two nested circles centered at the origin, rendered as an SVG viewBox with a range of -100 to 100. The outer circle has a radius of 50 and a fill of rgb(0,122,176), while the inner circle has a radius of 10 and a fill of rgb(162,207,225). The example uses the SVG `<circle>` element directly within an inline `<svg>` tag, with no JavaScript libraries or external data sources involved. It demonstrates a minimal, static visualization of hierarchical proportions through simple geometric layering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e5d882ac9dbd4daa967b9b5271a45185?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
