Simplify and enhance your visual workflow. Discuss ideas with comments, chat, video chat, and screen sharing. Review versions of your diagram to track changes. In today’s article, we will tell you how to make a data flow diagram quickly and easily. Share and edit the same diagram, at the same time.
It also supports other types of UML diagrams like Use case, DFD, and ER. This sequence diagram generator lets you pick a suitable template to match the common processes or scenarios. While you can draw a DFD by hand, it is best to use an online DFD maker.
