{"version":"1.0","type":"rich","title":"yes","description":"This example displays a single word, \"before,\" in large text that transitions to \"after\" over a 2.5-second fade, then immediately repeats by appending a new element. The animation loops indefinitely using an infinite `while(true)` loop. It leverages D3 v7’s `d3.select` to target the body and `.transition()` with delay and duration settings to toggle text content. The page is a bare HTML document with embedded JavaScript, demonstrating a minimal CSS-free animation cycle driven by D3’s DOM manipulation and transition API.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
