 Visualization is important, because
 \begin{itemize}
  \item can give essential insight into dynamics
  \item can detect errors much better than just looking at numbers
  \item necessary for publications
  \item can be good advertisement (cover pages ...)
 \end{itemize}
 Different visualization types:
 \begin{itemize}
  \item 1D/2D: most of published pictures
  \item 3D: usually done for movies
 \end{itemize}
