Visualised are 25 among the most important world's metropolis. Cities are grouped into 5 main temperature zones according to their latitude; and horizontally ordered according to their longitude. Each city identity is represented by a multiform polygon: illustrating and correlating it's area (square meter), number of inhabitants, number of turists per year, tallest building's heights, and average cost of houses according to real estate parameters(square meeter)  Further information to complete cities "id-card" are provided: age of the city, average temperature and average rainfall quantity. Latitude and Longitude not only determine rain and temperature: we discover they influence several urban characteristics indeed. (Lisbon and Honolulu seems exactly alike, what a surprise!)
