[BlindMath] How do I create a flowchart?

[Pranav Lal]

Hi all,

I need to create a flowchart. This is for a presentation at work. The most
efficient way  may be to get a sighted person to handle this task but I need
to edit that chart if I must. LaTEX seems to have this capability but I
don't fancy using it for one flowchart unless I must. This is because I have
not used LaTEX before. 

I have thought about using  scalable vector graphics but that appears to be
tedious as I would have to handle all the work of specifying coordinates for
each element.

Anyone any thoughts?  I am not in a position to buy software. I am willing
to write code if I must. I can use either Windows or  Linux.
