The code creates the mask with an ellipse element, then appends rectangles with a `mask` attribute referencing that ellipse. It uses vanilla JavaScript DOM manipulation, `document.createElementNS` for SVG namespacing, and `window.innerWidth/innerHeight` to size the scene.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/041d240a54d24afaaf05e5a7848ac9cd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
