{"version":"1.0","type":"rich","title":"Episode 3: Sol LeWitt in Vanilla JavaScript version 6","description":"This interactive SVG artwork reproduces a Sol LeWitt-inspired geometric composition using vanilla JavaScript and the SVG DOM API. It displays a grid of vertical rectangles overlaid with three white circles, plus a second grid of horizontal rectangles masked by three additional circles via SVG `<mask>` elements. The code generates 200 rectangles per grid programmatically, sizes elements relative to the window dimensions, and calls the Web Animations API’s `animate()` method with empty keyframes, preparing the shapes for potential motion while no visible animation occurs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b21157b97e44dd8bda6e3858fd43c3c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
