Wavefont

Wavefont is a variable font with Weight, Round, and Vertical Alignment axes for rendering data like waveforms, spectrums, diagrams, and bars. Wavefont bars correspond to values from 0 to 100, assigned to different characters: 0-9 chars are for simplified manual input with step 10 (bar height = number). a-z/A-Z for manual input with step 2, softened at edges a and Z (bar height = number of letter). U+0100-017F for 0..127 values with step 1. letter-spacing CSS property with ch units is useful to adjust distance between bars, 1ch === 1 bar width. To contribute, see github.com/dy/wavefont
