Process Types Graphic

The cover of Introduction to Functional Grammar (2nd Edition) by Michael Halliday (Arnold, 1985) featured a graphical version of the array of process types in English identified by Halliday. As well as it being a very attractive image, I have always marvelled at the simplicity and explanatory power of this illustration. The relationship between the process types and how they are realised in English is explored further in both IFG and "Construing Experience through Meaning" by Halliday and Matthiessen. Unfortunately, even in  this digital day and age, I have yet to find a good quality version of the image. The best on the net is here - it looks like a scanned and trimmed copy from the cover.
So, I tried to re-create the image, if not in detail at least in spirit. My apologies to Michael Halliday and the illustrator if my version does not match up to the original, and I will be more than happy to remove it if someone feels it is infringing a copyright. In the meantime, I will use it where I can, remembering to acknowledge it wherever possible.
