{"version":"1.0","type":"rich","title":"Make Something: Fork of Mouse Follower","description":"This example demonstrates a paint tool where a circle follows the mouse and leaves a trail of colored dots. Users draw by moving the pointer, cycle through nine colors by clicking, and adjust brush size from five preset values by right-clicking. The visualization uses a unidirectional data flow with a custom `viz` function and a `setState` callback. D3 selections handle mouse events and append SVG circles dynamically, while a text label shows the \"Paint!\" instruction in the center-top of the viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e75c20b11ce14300a1750f22c923199e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
