WebSequenceDiagrams Notation

March 01, 2016 #uml

https://www.websequencediagrams.com/ supports notation for synchronous calls, asynchronous calls, return calls and activations.  These features are useful for documenting complex interactions with some of the operations happening in the background.  The example below illustrates these interactions (see https://www.websequencediagrams.com/examples.html for full documentation).
