Try "Adelaide, South Australia". It was an actual planned city, and the city centre for the most part is a very easy to navigate grid. North Adelaide (the other grid you'll see to the north west just above it) also planned in the same way, but just across the river and smaller. Probably one of the best "planned cities" I've seen on things like this.

Ah Chandigarh. Good choice. The beauty of this city is evident in even this minimalist drawing.
