{"version":"1.0","type":"rich","title":"SVG Animations","description":"This example shows a single red rectangle centered on a blank SVG canvas. Hovering the mouse over the rectangle triggers a smooth CSS transition that changes its fill color to green and expands its stroke thickness from 20 to 100 pixels over 3 seconds. The code uses raw SVG elements inside an HTML page, relying on the CSS `transition` property to animate the state change. The rectangle’s starting dimensions and position are set via SVG attributes, while the hover effect is defined using the `:hover` pseudo-class.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4b1dc5b5221b419f945fc5e81b599dd2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
