{"version":"1.0","type":"rich","title":"Lesson1","description":"This example shows a simple HTML page displaying the message \"Hello HTML!\" in large, centered text. It demonstrates basic web rendering using CSS for styling and a plain HTML structure without external libraries or frameworks. The page uses the `.message` class to set font size and text alignment, and the content is static with no JavaScript interaction or data visualization. The example serves as a minimal introduction to HTML and CSS, matching the title and serving as a starting point for further lessons.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1661d29b62254fecb265058a09756209?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
