How to do set diagrams (NOT Venn Diagrams - see image for an example) in Microsoft Word

Question

I'm trying to create a diagram to illustrate set relationships in Microsoft Word. I'll admit that I can't remember the actual name of this type of diagram and I've been having trouble finding out what it's called (in fact, if someone could remind me of its name I'd appreciate it).

As an illustration, the Wikipedia article on bijections has a diagram that looks like what I'm trying to do:

Or, more specifically, something like this:

Does Microsoft Word have a tool for this? My first thoughts were to use SmartArt or Equations Editor, but if it's possible to do that in those it's not obvious to me how. Or am I going to have to use the Drawing Canvass for this? (I'd rather not have to do that though because it seems like the diagram would be a lot more professional-looking if there was a built-in tool to do that specifically).

I unfortunately do not have Visio by the way.

Answer 1

You have to draw it with the "Shapes" option on the Insert tab. That option has most of the tools you need in order to draw the diagram.

1. Oval for the set
2. Arrow lines
3. Text Boxes

In order to get the desired look you have to tweak each shape preferences: for the oval disable the shape fill and change line color. For the arrow choose the desired end arrow style. Once you have finished your diagram select all the components and "group" them in order to prevent unwanted changes while moving it around the document.
