{"version":"1.0","type":"rich","title":"Re-create Marks & Channels Graphic","description":"This example recreates a marks-and-channels graphic by drawing a curved line through a set of six predefined points. The path uses D3’s `line` generator with `curveCardinal` interpolation to produce a smooth spline, while small circles mark each data point. The code selects the SVG `path` and appends `circle` elements for every point, using raw coordinate arrays from the dataset. Rendering is done with D3 v5 and SVG, with the line styled via CSS as a gray, unfilled stroke.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ce600276a8da4322952dcf33171bad43?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
