    $\begingroup$ The FAQ says: "Do not post off-topic questions" - Then you make a question and name it: "Off Topic Question". Because the FAQ is for weak people! XD $\endgroup$

    $\begingroup$ For example this questions seems useful: Software for drawing geometry diagrams and Looking for a Drawing Program. Maybe if you search in questions tagged math-software, you can find several other similar questions. $\endgroup$

    $\begingroup$ On a related note, I'd love to see tikz support on MathJax. (I ain't holdin' my breath for that one, though.) $\endgroup$

    $\begingroup$ @Alexander: There is a 3rd-party plugin called XyJax which is a xy support for MathJax. It's unlikely to be assimilated into the main code, or get supported by SE anytime soon methinks. $\endgroup$

  • $\begingroup$ I'll add link to TeX Community Polls from TeX.SE. You can see there what software (La)TeX users prefer for creating various kinds of diagrams. $\endgroup$

In this answer I posted the following plot created in $\mathrm{\LaTeX}$, using the TikZ package.

Or a contour such as this one

    $\begingroup$ The certainly isn't the quickest solution, but it allows you the most control. I wish I had learned to use tikz much earlier... $\endgroup$

  • $\begingroup$ @user1729 You are right! I only know how to draw simple plots and contours. $\endgroup$

    $\begingroup$ I had to draw a "bouquet of circles" once, which was pretty difficult. I wanted to draw a graph with a single vertex and two loop edges, and then some dots to signify that there were some edges I hadn't put in. There were arrows and labels everywhere! It took me a long, long time to figure out how to do it, but my tikz is certainly better as a result! $\endgroup$

You could use:

  • Geogebra

  • Mathematica

  • Wolfram Alpha

  • SageMath

It depends on the depth of the question. But for the questions you are making, I guess Geogebra is enough.

When in need for diagrams used in category theory and some closely related fields, Presheaf.com can help you out.

I was pointed to it by Martin in this comment.

I use Microsoft Visio to draw contours. It's not ideal, but the elements are all there and I use it for my everyday work.

Usually, as you may find out from my answers; I use my handy works or use Maple 17. Sometimes, I really need a Blackboard.

I use Powerpoint, Excel, Mathematica, and CAD software.

Other packages that seem pretty good (but which I don't use) are Inkscape and GIMP.

I don't understand the "portable" comment. Regardless of which package software I use, I typically just grab a screen shot to post here. So the file format used by the software package is irrelevant.
