The origins of chart graphics (e.g., bar charts and line charts) are well known [30], with the seminal event being the publication of William Playfair’s (1759-1823) The Commercial and Political Atlas in London in 1786 [26]. However, the origins of graph drawing are not well known. Although Euler (1707-1783) is credited with originating graph
theory in 1736 [12],[20], graph drawings were in limited use centuries before Euler’s time. Moreover, Euler himself does not appear to have made
significant use of graph visualizations. Widespread use of graph drawing did not begin until decades later, when it arose
in several distinct contexts. In this short note we present a selection of very early graph drawings; note the apparent absence
of graph visualization in Euler’s work; and identify some early innovators of modern graph drawing.
A mathematical graph consists of a set of nodes and a set of edges. An edge connects a pair of nodes.
