How do I Create 9 objects not overlapping?

Hello people can someone explain to me how I can create 9 objects as in the example?

I know I need a loop, but what's next?

You can use two "for" loops to draw the objects, one for the grid width, one for the grid height:

In this example you can change the grid using the gridWidth gridHeight and margin variables.

Thanks man! it works!
