A grid of circles occupies the canvas, each circle’s position and size derived from a force-directed layout. The visualization shows a network-like arrangement where nodes cluster and repel, creating organic spacing. Using `d3.forceSimulation` with `forceManyBody` and `forceCollide`, the code updates node positions on each tick, redrawing them via Canvas 2D API calls. A title bar is styled via CSS, and the entire scene resets when the page reloads, as noted in the README. The rendering relies on manual canvas drawing rather than SVG or WebGL.
