For the back-story behind this typographic experiment, The Anatomy Of a Thousand Typefaces, @getFlourish have a comprehensive post over on Medium.
GetFlourish: “The Anatomy Of a Thousand Typefaces aims to analyse visual characteristics of typefaces, and to make them explorable through a web interface.
The data reveals shared characteristics between typefaces, but also shows the misfits and extremes along the distribution of values such as contrast, x-height, width or weight.
For demonstration purposes, the collection is limited to the Google Fonts Library, but theoretically applicable to any font library consisting of TrueType Fonts. This project wouldn’t be possible without OpenType.js”
