{"version":"1.0","type":"rich","title":"test","description":"This example demonstrates a static SVG rectangle that animates its width in response to a button click. The visualization uses D3.js to select the HTML body element, create an SVG container, and draw a rectangle. When the button triggers the `trigger()` function, the rectangle transitions its `width` attribute from 50 to 400 over a duration of 2000 milliseconds with a 100-millisecond delay, before being removed from the scene. The page relies on inline JavaScript and D3’s selection and transition APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0b1852e659f74fb7aeb13651ad96ddb9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
