D3.v4 force simulation animates hundreds of small blue circles that scatter randomly, then coalesce to form the word "Dasein". A larger invisible circle follows the mouse, disrupting the assembled text as it moves across the screen. The text shape is generated by rasterizing the word onto a hidden Canvas, sampling pixel positions with `getImageData`, and applying those coordinates as force targets via `d3.forceX` and `d3.forceY`. A gooey SVG filter blends overlapping circles into a fluid, cohesive mass.
