Visio Technical has many electrical shapes that other versions of Visio doesn't have. I have made simple schematics using Visio in the past and if you know how to save the shapes you should only have to make them once. I much prefer AutoCAD Electrical. It is more complicated but much more powerful and is used much more in industry. Knowing how to use it can be a large asset in a job search.
I posted the schematic I made for our robot this year as a .pdf, see below. It was made in AutoCAD Electrical as a .dwg which can be opened in Visio and converted. Let me know if the .dwg version would be helpful.
