📐 Measure Theory: Riemann vs Lebesgue

Interactive canvas demo comparing Riemann integration (x-axis partitioning) against Lebesgue integration (y-axis / level-set partitioning) on the Dirichlet function, plus an animated Cantor set construction showing removed-length approaching 1 while Lebesgue measure of the remainder tends to 0.
