SPARKS

Summary from the TLDR newsletter

Sparks is a typeface for creating sparklines in text without code. It uses OpenType's contextual alternates feature to perform simple replacement operations on numbers. Sparks works on desktop and on the web without JavaScript (but it requires a browser that can make use of OpenType features in text). It is currently compatible with Microsoft Word 2010 and later, Apple Pages, Adobe Creative Cloud applications, Chrome 33+, Safari 6+, Firefox 4+, and Internet Explorer 10+.
