Integers, rationals, irrationals — and the gaps between them
Pan and zoom along the number line. Toggle layers to see integers (discrete lattice), rationals (dense but holey), and famous irrationals. Zoom in to watch rationals multiply; zoom out to see structure emerge.

Zoom in to see rationals become denser — between any two, infinitely more exist.
Yet irrationals fill the "gaps" that rationals leave. The reals complete the line; the rationals alone cannot.
