{"version":"1.0","type":"rich","title":"Hello Canvas","description":"This example shows an HTML5 canvas that fills its entire 960-by-500 pixel area with a solid red rectangle. The code acquires a 2D drawing context using the canvas `getContext` API, sets the `fillStyle` to red, and calls `fillRect` to cover the full canvas bounds. It serves as a minimal starter template for rendering graphics, with CSS that removes page margins and hides overflow for an immersive full-window display.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c5eae688b0c4bc2a86af5709744a7bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
