I know this is older but I'm surprised by the "Is redrawing 110K glyphs (with metrics and kerning and combining attributes and hinting) too hard?" I used to do typography. A plain, unoriginal typeface with 255 straightforward latin-# oriented letters is at least a couple days of work; probably a couple weeks; couple months for truly good work. 110K is the equivalent of 400+ faces with much harder metrics and such. 15,000 hours of work or drastically more; so at least 7 or so years. So, kinda hard.

let's be honest, print-and-play is A LOT of work (printing, cutting, laminating, sleeving, etc) and it is not everyone's cup of tea.

SankeyMATIC builds on the open source tool D3.js and its Sankey library, which are very powerful but require a fair amount of work & expertise to use.
