   Krdict Explorer — spider-web constellation view.

   The metaphor: each word is a star; clicking pulls that star
   to center and reveals its constellation of related words.
   Dark space-like canvas with thin glowing lines for the web
   feel, foreignObject overlays render the labels so we get
   crisp HTML typography inside the SVG layout.
