{"version":"1.0","type":"rich","title":"epi 5 d3 selection and exploration","description":"This example shows a dynamic point cloud of fifteen circles that continuously orbit and pulse in size around the screen’s center. A thick, fixed purple polyline connects the points in sequence, while the circles themselves are rendered in cyan with a thin stroke. The animation updates sixty times per second via `setInterval`, using D3’s `line` generator and `select` API to bind new data to SVG `path` and `circle` elements. The data is generated procedurally with sine and cosine functions, varying each point’s position and radius over time, with no external dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
