There is a myriad of graphics programs on Linux: graphviz/dot, ditaa, plantuml, tikz, gimp, inkscape... There are many more. Some are general, some are more specialized. Russell mentioned Visio but afaik that's Windows only. Processing Processing code through a babel process should be entirely processable too :-) Once you produce output in some format (png, jpeg, svg, postscript - whatever your emacs is capable of showing through the image.el package[fn:1]), you can add a link to it in your org file. Then you can toggle inline images on or off with C-c C-x C-v (or C-u C-c C-x C-v if you have captions). Fundamentally, that's it - but of course, people have been coming up with streamlined ways to do all that (e.g. Max M's org-screenshot to take the most recent example). Footnotes: [fn:1] Mine can do png, jpeg, svg, xpm, but not postscript, even though image-type-available-p says that it *is* available - there are other formats that should also work, but that I have not tried: gif, pbm, xbm, bmp, tiff. Not sure why postscript does not work for me. On linux, the various image types require that emacs be built with the various libraries. On Windows, I think they are dynamically loaded, if present. -- Nick
