{"version":"1.0","type":"rich","title":"Multicolor Mouse Follower","description":"This example demonstrates how a visualization can maintain multiple independent pieces of state that respond to different user interactions. A circle follows the mouse's horizontal and vertical position through mousemove events, while clicking randomly changes its fill color and opacity using a custom color generator. The visualization uses D3.js version 7 with the join pattern to bind SVG elements, separating the state management logic from the rendering function that updates the circle's attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c38d8c66db0342148adcc44192c2b9c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
