{"version":"1.0","type":"rich","title":"D3 Selection Exploration","description":"This example demonstrates D3’s data join and selection patterns by animating a row of circles whose count and vertical positions oscillate with a sine wave. The code uses `d3.select`, `d3.range`, and `selectAll().data().join()` to update SVG circles at 60 frames per second, while a commented-out version shows the older `enter()`/`merge()`/`exit()` workflow. The visualization renders directly into the browser window via an SVG element sized to `window.innerWidth` and `window.innerHeight`, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9146577933834aa59cfb4429830de4f9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
