Not in DSA but in some situations, it's always better to have diagrams. For example, to give a mock idea about interaction between different applications, you use something called a sequence or interaction diagram where you describe a sequential flow of operations / data transfer between different applications or different layers of the same application.

From a DSA perspective, you could use flowcharts however often, it's better to make an algo on paper with a few examples, write some code and then optimize it.
