Although the work of Gerd Arntz (1900-1988) is usually associated with the information graphic system known as Isotype (International System of TYpographic Picture Education), Czech artist Augustin Tschinkel (1905-1983) also worked with the system's founder, Viennese social scientist Otto Neurath (1882-1945). I think the following Isotype catch-phrase reflects the system's philosophy best, "To remember simplified pictures is better than to forget accurate ones".

Gerd Arntz, Unemployed, 1931 woodcut.
Explanation for the above woodcut:
At the top, the rich cash their stock and entertain themselves with perversities or idleness, while the worker toils at the assembly line (center) and the unemployed (bottom) are kept in check by the military. The 'little man' drawn by Arntz here returns in the visual statistics as the Isotype pictogram of the unemployed; with his head between his shoulders and his hands in his pockets.
