The Web Services Choreography Description Language (WS-CDL) is an XML-based language for specifying business protocols for \emph{web services enabled} collaborative processes. The use of visual notations in modeling web services choreography has so far been done in an ad hoc fashion as seen in the literature. This paper presents a choreography example in four different visual modeling notations and compares them with regard to the semantics of WS-CDL. The results are useful for establishing a reliable visual approach to modeling web services choreography.
