{"version":"1.0","type":"rich","title":"Fork of smiley d3","description":"This example shows a large yellow circle centered in an SVG canvas, created as a simple smiley face placeholder. The visualization uses D3 version 6, specifically the `d3.select` method to target the SVG element and read its width and height attributes. The code appends a circle with a fixed radius equal to half the SVG height, positions it at the center using those dimensions, and fills it with yellow. The SVG has a width of 960 pixels and a height of 500 pixels, with text styling set to a very large font size in the page’s body.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/31a1ee5431ee41f590fd4a502197d8f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
