Grid help, Processing

The document describes code for generating raster sketches by iterating through a grid defined by variables gridX and gridY. Each iteration draws an ellipse or rectangle at coordinates determined by multiplying i, j, and gridSize. Later examples add transformations, random colors, and conditionals to vary the rendering within the grid.
