{"version":"1.0","type":"rich","title":"pro_1","description":"This example displays a set of seven semi-transparent circles, each with a unique color and varying size, arranged across a pale green background. The visualization uses D3 v7’s selection and data-join methods to bind an array of hardcoded position and radius values to SVG circle elements. The `viz` function creates an SVG canvas sized to the container and renders each circle with specified `cx`, `cy`, `r`, and `fill` attributes, while a fixed opacity of 0.7 gives the shapes a layered appearance.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a85ffc536fda4393889b0b139ff71f36?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
