[developers] type hierarchy visualization

[Woodley Packard]

Nice pictures, Glenn -- that's fun.  I always enjoy creative ways to visualize data.

If you feel like spending more time on that visualization (which I doubt?), you might make a version that excludes the inferred GLB types -- that would remove several "tumors" in the graphs.  Since they are not part of the authored work, I'd be tempted to consider them less indicative of the level of knowledge encoded.

There's another similar "tumor" that shows up in the Thai grammar, which would perhaps be trickier (and perhaps less desirable) to factor out: the matrix authors explicitly put all the glbs of the head types in, but I believe only a few of them are actively used in any particular matrix grammar (someone should correct me here), so it would be interesting to see what the picture looks like when some of those less interesting types are excluded.

Aesthetic kudos to the JaCY developers for avoiding any of those significantly sized GLB clumps.  I do see several in the ERG (though maybe none quite so impressive as the head types in the matrix).

Cheers,
Woodley
