{"version":"1.0","type":"rich","title":"D3 Selection Exploration","description":"A set of circles animates smoothly across the screen, their count and vertical positions oscillating sinusoidally over time. The example demonstrates D3's data join pattern using `selectAll`, `data`, and `.join('circle')` to handle enter, update, and exit states. The SVG is sized to the full viewport, and an interval updates the dataset every 100 milliseconds, repositioning each circle via `attr('cx')` and `attr('cy')`. The source data is generated on the fly with `range` and `Math.sin`, rendering with D3 v6's SVG and animation capabilities.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bf06f7e41da8468e81d7954ee25ffe2a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
