{"version":"1.0","type":"rich","title":"Fork of D3 Selection Exploration","description":"Animated circles move in a sine-wave pattern across an SVG canvas, with their vertical position and radius oscillating over time. This fork dynamically updates the number of visible circles between 5 and 15 based on a continuously incrementing time variable. The code uses D3 v7's `select` and `range` functions, along with the data-join `.join()` method to efficiently add and remove circle elements each animation frame.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
