Industrial Philadelphia : from the infant industries of two centuries ago to the giant of today
Industrial Philadelphia, published in 1912 by the Foreign Trade Bureau of the Philadelphia Commercial Museum, is a promotional survey by John James Macfarlane tracing the city's manufacturing from colonial-era infant industries to its modern scale. The two pie charts show Philadelphia's industries by wage earners in thousands and by total value of products in millions of dollars, with wedge sizes sorted by rank and labels set radially around the circle. A designer might take from them the plain radial-label layout and the ranked wedge arrangement, which read clearly as an information graphic.
