Hilbert curve is a type of space-filling curves that fold one dimensional axis into a two dimensional space, but with still keeping the locality. It has advantages to visualize data with long axis in following two aspects: easy to visualize clusters because generally data points in the cluster will also be close in the Hilbert curve.

Web1st iteration there are 4 elements which map to (0,0), (0,1), (1,1) and (1,0) 2nd iteration has 16 elements, by dividing each point into 4 sub quadrants.
