A 1925 NASA Technical Reports Server scan of N.A.C.A. Technical Memorandum No. 306, a technical memorandum issued for engineers and aeronautical researchers. Its single figure is a set of line graphs plotting altitude in metres against temperature from -15 to 100 across several sets of labelled curves, with sparse black linework on a grid. A designer might borrow the clean grid and crisp data-plot vocabulary for minimal diagram or infographic layouts.
