{"version":"1.0","type":"rich","title":"Course_start","description":"This example shows a set of SVG shapes—two circles, a rectangle, and a line—on a 960 by 500 canvas, with interactions triggered by hovering. The circles and rectangle respond to mouseover events with CSS transitions: the first circle changes fill and stroke width, the second also scales, and the rectangle rotates. Built with plain HTML, CSS, and JavaScript, it uses React only as a starter framework, with all styling defined in a style block and no external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/91d62b6898334370b0c4dc245295f9ca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
