{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example displays a blank, purple visualization with three concentric circles centered within an SVG element. The circles are rendered using the SVG `circle` element, with the outer circle and two inner circles all having the same radius and position, creating a single overlapping shape. The code uses d3’s `select` and `svg.append` methods to build the graphic, while the `index.html` file loads the D3 library from a CDN. The page is styled with CSS to center text at a large font size, and the rendering approach relies on SVG primitives.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8f0eff7bc2d84d698791ed4c893ed0a1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
