{"version":"1.0","type":"rich","title":"svg基础知识","description":"A minimalist demonstration of Scalable Vector Graphics (SVG) fundamentals. The example presents a single red circle rendered inside an HTML `<svg>` element, using the standard SVG `circle` tag with `cx`, `cy`, and `r` attributes to define position and radius, and `fill` for color. The page is plain HTML with inline CSS and JavaScript, showcasing the basic syntax required for embedding vector graphics directly in web documents. This serves as an introductory reference for SVG's coordinate system and shape elements, with no external libraries or data sources involved.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6de93fb0097146f29389b4877e02a201?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
