{"version":"1.0","type":"rich","title":"Hello HTML","description":"This example shows a single red square rendered in SVG, which transitions to green with a thicker border when hovered. The page uses plain HTML, CSS, and JavaScript, with a 1000x1000 SVG element containing a `<rect>`. The CSS defines the shape's stroke, fill, and a 3-second transition on those properties, triggered by the `:hover` pseudo-class. No external libraries are used; it demonstrates basic SVG and CSS interactivity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2fce1c4c1f87401bb57339e21b5f93b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
