MAPs

A map is a visual representation of an area. A Map represents any space, real or imagined, without regard to context or scale. There are lot of maps such as Mind-Map (used to represent words, ideas, tasks, etc.), Concept-Map (that show diagrams of relationships among concepts), Topic-Maps (designed as a standard for the representation and interchange of knowledge) etc. Maps always seem to help us find our ways. Maps help us to discover.

Here I find an interesting below Map that identifies the most popular social networks in the different countries worldwide. The colors are the house colors from the respective networks.
I expect it may be useful to you.
