Structure your workflow by collapsing parts of it into metanodes.












Exercise: MetanodesBelow you see a workflow that performs a number of different data wrangling tasks. Actually, you completed them yourself earlier in the course!Structure the workflow by metanodes so that each orange annotation and the nodes inside it make one metanode. The nodes that are notinside any annotation can be left as they are.
