{"version":"1.0","type":"rich","title":"SVG Fundamental","description":"This example creates a full-screen SVG image built entirely from programmatically generated rectangles. It demonstrates two different mask patterns that reveal a central circular area, with one mask applied to horizontal bars and another to vertical bars. The code uses D3.js version 6.6.1, specifically the `selection` module, alongside vanilla JavaScript DOM manipulation with `document.createElementNS` and SVG attributes. The rendering approach shows raw SVG element creation without using D3's data join or helper functions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bb3b9b352ec44a94a69c1e6532e7e2a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
