{"version":"1.0","type":"rich","title":"Fork of D3 Starter","description":"This example demonstrates a simple sunrise and sunset animation using a yellow circle that moves vertically within an SVG canvas. The circle alternates between two positions—descending to the bottom and rising to the top—via a CSS `@keyframes` rule named `sunrise-sunset`, applied with an infinite alternate timing function. The markup also includes a static SVG circle and a brief demonstration of D3 version 7's `select` function to insert text into the body. The animation runs in a 500x500 viewport, showing basic CSS-driven motion without JavaScript interaction or external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c393ab5f77a405b9a3dd8460558b752?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
