What tools are out there for creating mathematical illustrations in a what-you-see-is-what-you-get mode?
Having struggled with tikz for several years, I've found creating figures in Omnigraffle (https://www.omnigroup.com/omnigraffle) to be a liberating experience. (And they have good tech support.)
The webpage http://wiki.illustrating-mathematics.org/wiki/What_tools_do_we_use%3F mentions Inkscape and Illustrator; how do they compare to Omnigraffle for flexibility and ease of use?
If other people know similar systems that they like better, I'd love to know about them.
