The commercial sector has enthusiastically taken up infographic design within the last decade or so as a means of communicating large quantities of otherwise difficult to assimilate information in a single easily understood and visually attractive product. Whereas Neurath principally designed his isotype language for people who had poor literacy or numeracy, the modern infographic is designed for quick assimilation to match the frenetic lives of a general public who are often unwilling or unable to spend time focusing on a piece of information long enough to understand it 6. Isotype array infographics communicate part to whole relationship between positive and negative outcomes and may be suited to visualisation of dichotomous information such as riskreward ratio of statin usage The philosophy of isotype picture language is elaborated upon during discussion of figure 3. Neurath and his associates produced a vast library of communicative graphics addressing a variety of socio-political topics, many of which remain in use today. Another historical example of data visualisation came in the early twentieth century in the form of Otto Neurath’s isotype picture language 5.

This was achieved using a type of infographic called a polar area diagram, which is also discussed later in this article.

Other noteworthy examples of data visualisation can be found in the nineteenth century.
