{"version":"1.0","type":"rich","title":"Arrow Mouse Follower","description":"An arrow follows the mouse cursor across the full viewport, rendered as an SVG path with a red marker arrowhead and thick stroke. The example demonstrates unidirectional data flow: a mousemove event triggers a state update that redraws the path. It uses D3 v7’s selection joins and `setState`/`render` pattern to update the SVG, with the path positioned relative to the cursor’s x and y coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3766d5c273e4eaea9c9e0d392654f9c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
