{"version":"1.0","type":"rich","title":"COPY Fork of HTML Starter, Hello World","description":"This example demonstrates a simple interactive color-change effect on a web page. It shows a styled \"Hello World\" message and a button, where clicking the button toggles a pink background class on both elements. The behavior is implemented with vanilla JavaScript event handling, using `document.querySelector` and `classList.toggle` in response to a click listener. The rendering approach is plain HTML and CSS, with no external libraries or data sources; the layout uses CSS grid for centering and transitions for smooth visual feedback.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/94c8b753fb9249689275560c387a2d07?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
