/**
 * Demo for rendering a 10x10 grid of rectangles within the bounds
 * of the canvas. Each rectangle's position is calculated relative to its anchors, filling the entire
 * canvas with evenly placed items.
 *
 * The rectangles are drawn using the default white color. The `place` function is applied to each
 * rectangle to position them dynamically based on their relative anchor points within the bounding area.
 *
 * This serves as a demonstration of positioning and rendering shapes in a structured grid layout.
