{"version":"1.0","type":"rich","title":"First lesson Hello HTML","description":"This example demonstrates a basic HTML page containing an inline SVG canvas with primitive shapes—circles, a rectangle, a line, and a path—styled using CSS. The shapes respond to hover events, smoothly transitioning their fill color and stroke width over one second. The SVG uses built-in shape elements, with CSS transitions applied directly to the `<rect>` and `<circle>` tags, while the path draws a green shape using SVG path commands. The rendering is pure SVG, with no external JavaScript libraries.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/12b346232ba34dbbb1aa0b0e7f0af462?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
