Integration As Accumulated Area

This animation shows how integration builds up total area under a curve by summing infinitely many thin rectangular slices. As the slice width shrinks toward zero, the sum converges to the exact area, illustrating the core idea behind the definite integral. A running total bar tracks accumulation alongside the curve, linking the algebraic sum to a geometric result. Useful for students meeting integral calculus for the first time and for teachers introducing Riemann sums before formal notation.
