{"version":"1.0","type":"rich","title":"cvg with css","description":"This example shows a single red SVG rectangle that transitions to yellow and expands its stroke when hovered over, using CSS transitions. The page is a bare minimum HTML document with inline styles, demonstrating how CSS `transition` properties animate changes to `fill` and `stroke-width`. A `rect` element within an SVG canvas responds to `:hover`, triggering a three-second all-property transition that alters its appearance. The code does not rely on JavaScript libraries or data sources, only native CSS and SVG markup.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58a3dd3effe1411780175414c1214963?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
