gMath creates graphs in Google Docs

Need to insert a mathematical graph into a Google doc?  Now you can, without having to copy and paste.  Try the gMath add-on for Google Drive (go to Add-ons...Get add-ons, then search for it) . One limitation is that it only graphs from -10 to 10 in both x and y.

 It also has an equation editor, but that requires LaTeX, which is harder than just using the built-in equation editor (Go to Insert..Equation).

Also, there is now the ability to insert graphs into Google spreadsheets and forms, which could be useful to create an assessment.
