How to make a freehand drawing in Microsoft Word?

Question

infographics

Often, when I write lectures in Word, I need to quickly draw some kind of figure, graph, etc., some kind of arbitrary drawing.
How to make an arbitrary drawing directly in Word?
Or maybe there is a program where you can draw a graph "by eye", i.e. without any formulas, but stupidly moving the mouse?

Answer 1

You draw in Paint, save, drag and drop the picture into Word, you can delete it, it will remain in Word.

Answer 3

In order not to mess with paint, I do this: I open a blank sheet in the browser or take a white field, then using app.prntscr.com/ru I create a screenshot, I edit it right there, namely, I draw anything (there are lines, inscriptions, a rectangle, and something else) and send it to the server, then you can simply drag the picture into word.
