{"version":"1.0","type":"rich","title":"Fork of HTML Starter","description":"This example creates an interactive SVG visualization by generating a series of horizontal stripes across the full canvas, with a circular mask applied to reveal only the central region. The code uses the raw SVG DOM API (`document.createElementNS`) to construct a mask element containing a white circle over a black rectangle, then appends 100 overlapping rectangular bands that reference this mask via `url(#circle-mask)`. The visualization employs React as the framework but relies on vanilla JavaScript for rendering, with the page adaptively sized to `innerWidth` and `innerHeight`. The result is a simple pattern of layered color bands emerging through a circular window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/03f03e545f294dbfb237a17038aa791d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
