{"version":"1.0","type":"rich","title":"testejs","description":"This example demonstrates a minimal web page that combines HTML, CSS, and JavaScript with canvas rendering. It displays a large “Hello HTML!” message while also drawing a red rectangle and a series of horizontal grid lines on a canvas element using the Canvas 2D API. A separate “Hello world!” text is injected into a div via `document.getElementById` and `textContent`. The source code uses vanilla JavaScript with no external libraries, showing basic canvas drawing commands like `fillRect` and `stroke`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/badb2312cf824398a782d5c0894a0ec3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
