| == Introduction ==
| |
| | |
| Visualization still takes place in a space with a limited number of discrete
| |
| pixels. The result of this often is over-plotting, clutter or other things.
| |
| Most of the time this structures are avoided. But sometimes this artifacts can be useful, because they might point out interesting structures in the data.
