{"version":"1.0","type":"rich","title":"Stage 2 of Sol LeWitt Reproduction","description":"This example reproduces the second stage of a Sol LeWitt wall drawing using raw SVG and JavaScript. It creates two circular masks over a full-window canvas, then draws 100 horizontal and 100 vertical stripes. Horizontal stripes appear only inside the first mask, while vertical stripes are visible outside the second mask, producing a grid that shifts from a solid square to an open circle at the center. The code builds all elements dynamically using `document.createElementNS` and sets attributes directly, with no external libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7ad11dbd604b4031823398951f58f8e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
