{"version":"1.0","type":"rich","title":"D3 Selection Exploration","description":"A set of 15 circles animates in a sine-wave pattern across the browser window, with each circle's vertical position and radius oscillating over time. The code uses D3 v6's `select`, `range`, and `data` join methods to bind an array of computed objects to SVG circle elements. A `setInterval` at roughly 60 frames per second updates the data and re-renders via the `.join('circle')` pattern, which handles enter, update, and exit states seamlessly.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
