{"version":"1.0","type":"rich","title":"T3 Test","description":"A field of 150 colored circles of random size, position, opacity, and color fills the browser window. Hovering over a circle reveals a styled tooltip displaying the circle's data (x, y, and id) in a table. The tooltip repositions to stay within the viewport, and the circle's fill color transitions to a new random color. Built with D3 v7, this demo uses selection-based event handlers (`mouseover`, `mousemove`, `mouseleave`) and D3's `transition` to animate the color change.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/21fc67e96ac04773a3883705a022b779?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
