RABBIT and cellular Automata

I am working on a school project and the site is in Dhaka Bangladesh. The city is extremely dense with residential and and manufacturing. I would like to graphically represent this density using a series of cubes varying in width and height on a surface. that would represent the density in the city. The effect im looking for is similar to Greeble in 3ds max. Ive been looking online at Rabbit and it seems to have a similar effect of Greeble. Unfortunately Ive had difficulties finding tutorials on how to use rabbit. Any advice and or help would be greatly appreciated. below is the affect I would like to create.
