{"version":"1.0","type":"rich","title":"HTML Starter, Hello World","description":"This example shows a minimal interactive HTML page where a click on a button toggles the background color of a displayed message and the button itself. The page renders a yellow-centered layout with a large green “Hello World” text and a light blue button. The interaction is handled by a JavaScript event listener that toggles CSS classes. It uses the Document Object Model (DOM) API via `querySelector` and `addEventListener`, with no external libraries or data sources.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1a4009e3fd33417abd7729fedf653104?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
