{"version":"1.0","type":"rich","title":"Exercise v3","description":"A reproduction of a Sol LeWitt art piece shows a black background with five colored circles that animate into place. Using D3.js, the code binds an array of circle objects to SVG elements, entering circles with a slow transition that delays each one and expands its radius from zero. Updates apply a fast linear transition to reposition existing circles, while exits shrink back to zero before removal. The rendering uses D3 transitions with `easeLinear` and explicit key functions for stable data binding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/1cbc9c74f716411d8019eb1891d33dc3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
