/**
 * Demonstrates how to draw circles distributed within two subregions of a rectangular area
 * using uniform random distribution and a hash-based method for randomness.
 *
 * The application divides the window area into two subregions, offsets the edges inwards,
 * and then calculates two circles representing these subregions. Points are then generated and drawn
 * within these circles using two different methods:
 *
 * - A uniform random distribution within the first circle.
 * - A hash-based deterministic random point generation within the second circle.
