The proper visualization and monitoring of their (ongoing) business processes is crucial for any enterprise.
Thus a broad spectrum of processes has to be visualized ranging from simple, short–running processes to
complex long–running ones (consisting of up to hundreds of activities). In any case, users shall be able to
quickly understand the logic behind a process and to get a quick overview of related tasks. One practical
problem arises when different fragments of a business process are scattered over several systems where they
are often modeled using different process meta models (e.g., High–Level Petri Nets). The challenge is to find
an integrated and user–friendly visualization for these business processes. In this paper we discover use cases
relevant in this context. Since existing graph layout approaches have focused on general graph drawing so
far we further develop a specific approach for layouting business process graphs. The work presented in this
paper is embedded within a larger project (Proviado) on the visualization of automotive processes
