{"version":"1.0","type":"rich","title":"Fork of Mouse Follower","description":"This example demonstrates a mouse follower where a circle visually tracks the cursor’s position across the viewport, serving as a minimal illustration of unidirectional data flow in a React-driven D3 visualization. The code uses D3’s `select` and `join` API to incrementally build an SVG and circle element, updating their `cx` and `cy` attributes based on mouse events. State changes trigger a re-render through the `setState` callback, with the initial position defaulting to the center of the window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/65323563a64c45079ecbb2e24844a8eb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
