# Software for creating simple X,Y graphs

I need to be able to plot X,Y graphs as well circles. I tried using octave but the functionality is just not there.

Does anyone have any recommendations?

I want to be able to generate graphs that are like this:

You can draw with or without a pre-formatted coordinate grid with $x, y$ axes, and can draw shapes of any sort. The learning curve is not at all steep, so you can be up and running shortly after downloading!
