{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example demonstrates a Sol LeWitt-inspired geometric composition rendered entirely in SVG. It shows a circular mask revealing a series of horizontal stripes across the full viewport. The code creates the mask using a white rectangle and a black circle, then draws 100 rectangles, each 20 pixels apart, applying the mask via the `url(#circle-mask)` reference. The implementation uses vanilla JavaScript DOM manipulation with `createElementNS` and `setAttribute`, avoiding any external libraries. The visualization is static, with the masked stripes forming the central visual effect against a clean, margin-free background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/895db14cec31404b8fc6cb6b57fca9b7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
