Visio in Microsoft 365 is a superb tool for creating custom diagrams to illustrate concepts that are difficult to explain through text. Here’s how to use it.

For only $30, plan out your network, project, floorplan, and more with the easy-to-use diagramming tools available in Microsoft Visio Professional.

That said, I don't especially care for Visio; it's unnecessarily complicated, and it costs money. Now, though, I can use Project Draw, a free Web app from Autodesk.

Google Docs Drawing is ok for some things, but lets see how it compares with its Microsoft Office equivalent--Visio.
