This Monte Carlo simulation estimates the area of a circle (radius 0.3, area 0.2827)
inscribed within a unit square (1 x 1).
It achieves this by randomly generating points within the square and
calculating the ratio of points falling inside the circle to the total
number of points. By increasing the number of generated points
the simulation demonstrates the convergence of the estimated area
toward the circle's true area, illustrating a fundamental application
of Monte Carlo methods.
