This is a website implemented using JAVA technology, so if your computer does not have the JAVA program installed, you won't be able to view this site. However, the functions provided by this website are very interesting. It provides statistical map trees of things that people care about. Statistical map trees are naturally more intuitive and vivid than mere statistics or even charts. This is precisely the key reason why this website is interesting.
For example, it provides a world population distribution map, "showing infographics about the world's population, land area, and population density. The greener the color, the higher the ranking; conversely, the redder it is, the lower the ranking."
