/**
* This demo sets up an interactive graphics application with a configurable
* display window and visualization logic. It uses a `HashGrid` to manage points
* in a 2D space and randomly generates points within the drawable area. These
* points are then inserted into the grid if they satisfy certain spatial conditions.
* The visual output includes:
* - Rectangles representing the bounds of the cells in the grid.
* - Circles representing the generated points.
