ISOTYPE Visualization

A very nice vintage data visualization in the ISOTYPE style via the Information is Beautiful blog.  ISOTYPE stands for “International System Of TYpographic Picture Education. It was an early infographical form, originated in the 1930s by Austrian philosopher and curator Otto Neurath ‘as a symbolic way of representing quantitative information via easily interpretable icons.'”

Playfair’s Early Data Visualizations

A data visualization by William Playfair from his book The Commercial and Political Atlas and Statistical Breviary, from the early 1800s.  Playfair pioneered many of the chart forms we know today, though the one above I find fascinatingly new, a sort of combination of the pie and bar graph.
