{"version":"1.0","type":"rich","title":"SVG Fundamentals","description":"This example demonstrates fundamental SVG rendering and styling using a single red rectangle with a black stroke on a 960-by-500 canvas. It shows how CSS transitions animate the rectangle’s fill color and stroke width over three seconds when hovered. The code directly uses the SVG `rect` element, CSS `:hover` pseudo-class, and the `transition` property in an HTML page with embedded styles. No JavaScript libraries are involved.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9215d7eb2f654d7a830f9753a4d1e582?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
