{"version":"1.0","type":"rich","title":"Point-Along-Path Interpolation","description":"A single point traverses a pair of Catmull–Rom splines, using the SVG `getTotalLength` and `getPointAtLength` methods to compute the point’s position along the path at each frame. The example also includes interactive behavior: clicking on the canvas creates new circles that move along the path with simple vector-based steering toward the mouse position. The visualization demonstrates how path interpolation can be combined with animated movement in D3.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-ed1e6e1a6915364ff5bf166e99057436?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
