{"version":"1.0","type":"rich","title":"Hierarchy Tree of US Counties","description":"This example presents a minimal HTML page that displays a large, centered \"Hello HTML!\" message using CSS styling. The layout relies on a simple flexbox-free approach: a div element with a font-size of 13em and text-align set to center. The page uses no external libraries or JavaScript functionality, focusing solely on static HTML and CSS rendering. It serves as a bare-bones starter template for web development, demonstrating basic document structure and style application without interactive features or data visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/98df05278f634962beee963ebc139a3f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
