{"version":"1.0","type":"rich","title":"Untitled","description":"A simple HTML page containing a 100-pixel black square is animated inside a React application. The example demonstrates the `d3.transition()` API, which is used to smoothly change the background color of the `div` element from black to red over a duration of 3000 milliseconds. The page imports D3 v4 and uses `d3.select()` to target the container. The rendered output is a basic color transition, with no data input or complex rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bc1293501ec147a1b26d87b46bf9195d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
