{"version":"1.0","type":"rich","title":"Moving circle","description":"A moving circle follows the mouse cursor across an SVG canvas, changing to a random RGB color with each click. The visualization uses D3's data join pattern, binding arrays of null values to create and update a single circle and svg element on every state change. Mouse and click event listeners call a setState function that updates the circle's x and y coordinates to the cursor position or assigns a new randomly generated color.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
