Documenta<on – The Problem • Systems and soAware are evolving –> ”Document Dept”
• What is important and to whom? The sender or the receiver?

Explora<on SoAware Visualiza<on
• GeneraDng images instead of doing it by hand when we want to explore the informa<on (microstates).
• Informa<on visualiza<on is essen<al in making sense out of large data sets (microstates) by finding paVerns.
