Bollettino dell'Osservatorio della Regia Università di Torino, 1881 (vol. 16)
A bulletin of the Royal University of Turin's observatory for 1881, issued by the Turin astronomical observatory for a scholarly and scientific readership. Its pictures are meteorological charts for January 1881, with day-numbered grids and hand-drawn line graphs of barometric pressure, thermometer readings, vapour tension and relative humidity. A designer might take the plain ruled-grid layout and the rhythmic, waveringline traces as a model for data-driven graphics.
