WebHilbertCurve. 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.

Both the true Hilbert curve and its discrete approximations are useful because they give a mapping between 1D and 2D space that preserves locality fairly well. This means that two data points which are close to each other in one-dimensional space are also close to each other after folding. The converse cannot always be true. Because of this locality property, the Hilbert curve is widely used in computer science. For exam… WebMar 17, 2009 · The square in the Hilbert plot in Figure 1C consists of 2 8 × 2 8 pixels, i.e. the data vector is folded into the square according to the 8-th iteration of the Hilbert curve..
