SparkFonts: Sparklines as TrueType Fonts

"A key characteristic of the SparkMaker add-in for Microsoft Office is the typographical creation of sparklines by means of specifically crafted TrueType Fonts (TTF), the Bissantz SparkFonts.

The crux of SparkMaker is that each value of the input data is represented by one character which is formatted with an appropriate SparkFont. The SparkFonts embody bars, line segments, pies and other fractions of statistical diagrams. The concatenation of formatted characters results in a "textual image" of the sparkline. This way, you can work with the sparkline just like with normal text. For example, you can put it into table cells or insert it directly into your writings. Another quality is that the sparklines can continuously be scaled with the surrounding text, and printouts are razor-sharp."
