I'm guessing you're thinking about categorizing the list at

http://dlang.org/phobos/std_range.html

, right? ;)

That would, IMHO, be a nice usability/discoverability 
improvement, especially for new users!

:)

Further, I've thought about adding some kind standardized 
graphical explanation for the ranges and algorithms in Phobos.

I've Googled a bit on this topic, say:

"algorithm visualization"

but I can't seem to find any concrete work on this topic. Refs 
ideas anyone?

What file format would be preferred for such graphical 
descriptions? I'm guessing SVG would be a good contender.

A supercool thing would be if we, with the help of D's marvellous 
meta-programming and CT/RT-reflection, could auto-generate these 
visualizations.
