Fork of Hot Circles
Animated circles in vivid colors pulse and drift across a black canvas, blending via screen mode for luminous overlaps. The visualization reads a static CSV dataset of circle positions and radii, rendering each as an SVG element with a 2-second growth transition. D3’s selection joins handle enter, update, and exit states, while `transition` with `easeLinear` animates movement and resizing. Data coordinates drive the layout, with opacity set for subtle layering.
