About Datatype.

Datatype is a variable OpenType font that transforms simple text expressions into inline data visualizations—no JavaScript required. Using OpenType contextual alternates and ligature substitution, text like {b:30,70,50,90} automatically becomes a bar chart within your document.

Designed for seamless integration into text-based workflows, Datatype enables you to embed charts directly in emails, documentation, reports, and web content. The font supports three chart types: bar charts, sparklines (line charts), and pie charts, each activated through simple text syntax.

Chart Syntax:

  • Bar charts: {b:15,45,80,30,60} (up to 20 values, 0-100)
  • Sparklines: {l:10,40,25,70,50} (up to 20 points, 0-100)
  • Pie charts: {p:75} (single percentage value)

The font includes two variable axes for extensive customization: Width (wdth: 0-100) controls spacing and compactness, while Weight (wght: 100-900) adjusts line thickness and visual prominence. This enables designers to fine-tune charts for different contexts—from dense dashboards to prominent presentations.

Datatype uses the Contextual Alternates (calt) feature for bar charts and sparklines, ensuring broad compatibility across applications including Google Docs, Sheets, and Slides. Pie charts utilize Standard Ligatures (liga), which may require manual enablement in some environments.

Built with fontTools and licensed under the SIL Open Font License 1.1, Datatype brings the power of inline data visualization to any application that supports OpenType features.

PREAMBLE
The goals of the Open Font License (OFL) are to stimulate worldwide
development of collaborative font projects, to support the font creation
efforts of academic and linguistic communities, and to provide a free and
open framework in which fonts may be shared and improved in partnership
with others.

The OFL allows the licensed fonts to be used, studied, modified and
redistributed freely as long as they are not sold by themselves. The
fonts, including any derivative works, can be bundled, embedded,
redistributed and/or sold with any software provided that any reserved
names are not used by derivative works. The fonts and derivatives,
however, cannot be released under any other type of license. The
requirement for fonts to remain under this license does not apply
to any document created using the fonts or their derivatives.
