{"version":"1.0","type":"rich","title":"myHTML Starter","description":"A static SVG rectangle changes color and stroke width when hovered. The page uses HTML, CSS, and JavaScript, with a CSS `transition` property animating the `fill` and `stroke-width` changes over 3000 milliseconds. The rectangle is defined directly in the SVG markup, and the hover effect is triggered by the CSS `:hover` pseudo-class. The example demonstrates a minimal interactive styling technique without external libraries or data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cd24c990ee49461ab66270448a30e207?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
