The map shows six partial city plans from cities around the world, illustrating differently shaped city blocks. The plans are presented in two lines. On the first line, from left to right, are shown the cities of Curitiba in Brazil (triangular city blocks), Houston in the USA (square city blocks) and Mexico City in Mexico (rectangular city blocks). On the second line, from left to right, are shown the cities of Shanghai in China (a pentagonal city block), Singapore (hexagonal city blocks) and Athens in Greece (city blocks shaped like lozenges). Below the images there is a text block with the title, description and technical data.
