Airplane stability in taxying
A 1932 NASA technical report on airplane stability while taxiing, a technical document for engineers and aviation researchers. Its pictures are plain line graphs with grid backgrounds, showing straight lines labelled f = 0.1 to f = 0.5 plotted against axes a and b, with the lines fanning out from the origin. A designer could take from them a clean, restrained scheme of radiating lines and fine grid structure for data-style graphics.
