I just had an interesting experience installing the Julia charts package (Gadfly based on ggplot) on my Mac which I thought I would share as I know I and other folk have had trouble getting diagrams / Cairo to work on Macs. It installs homebrew and then all the required packages from its own repo (not sure what the homebrew terminology is for this - possibly a brewery?) so presumably guaranteeing that the installation is consistent and “just works”. I must say I was a bit surprised (I think I would have liked it to tell me what it was about to do) but it was entirely painless and I drew my first chart after less than 5 minutes. Something to bear in mind for making the barrier to entry to Haskell a bit lower.
