How are flow charts different from data flow diagrams?

Flow charts are used in designing a process, but data flow diagrams are used to describe the path of data that will complete that process.

Flow charts show all the steps needed to reach the data whereas data flow diagrams only show the flow of data in the system.

Flow charts explain functions whereas data flow diagrams define the functionality of the function.

All of the above

There is no difference between flow charts and data flow diagrams.
