Here is an example script that shows how to create a 2D array of objects and position them in a grid structure. Let me know if anything is unclear.

import viz
viz.go()

#Width, height of grid
GRID_SIZE = [10,5]

#Spacing between grid items
GRID_SPACING = 1.0

#2D array of blocks
blocks = []

#Iterate over x-axis
for x in range(GRID_SIZE[0]):
	
	column = []
	
	#Iterate over y-axis
	for y in range(GRID_SIZE[1]):

		#Create block (copy file from cache)
		b = viz.add('white_ball.wrl',cache=viz.CACHE_COPY)
		
		#Position block in grid
		b.setPosition(x*GRID_SPACING,0,y*GRID_SPACING)
		
		#Add block to current column
		column.append(b)
	
	blocks.append(column)

#Set color of block (3,1) to red
blocks[3][1].color(viz.RED)

#Add environment
import vizshape
vizshape.addGrid(color=[0.2]*3)
viz.clearcolor(viz.GRAY)

#Setup camera navigation
import vizcam
cam = vizcam.PivotNavigate(center=(0,0,0))
cam.rotateTo(0,10,-20)
