{"version":"1.0","type":"rich","title":"Piano spline","description":"This example visualizes a dataset of 88 (x, y) points—reminiscent of piano keys—by drawing a smooth Catmull-Rom spline through them in SVG. It uses a JavaScript implementation of the spline with adjustable parametrization (uniform, centripetal, or chordal) to compute Bézier control points. The chart displays red input-point paths, blue spline points with interactive hover highlighting, and a side panel listing values for each point, rendered via native DOM and SVG APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/961c74551b80442daf857dd9db9c025a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
