TK TYPE has a font called Chartwell that can be used to make simple pie, ring, bar and sparkline trend charts by exploiting the OpenType ligature features of your favorite publishing platform (e.g. InDesign).
You type values as normal numbers, coloring them as you like, concatenating them with “+” signs to make a chart, then turn on ligatures in your software. BOOM: Graph.
This is easily too clever by half. Which is why I love it.
OK, I got me a hammer. Where’s them nails at?
