3. Exposition of the American Negro, 1900 Paris Exposition
   [1]
   Introduction
   To help designers, artists, developers, and scholars seeking to implement
   or study the “Du Bois Style”, this document describes aspects of the
   visualizations created by W. E. B Du Bois' team for the 1900 Paris
   exposition [1].
   To learn more see “W.E.B Du Bois's Data Portraits Visualizing Black
   America” [2]. by Whitney Battle-Baptise and Britt Rusert and the
   Library of Congress collection “African American Photographs Assembled
   for 1900 Paris Exposition” [3].
   The sources above use plate numbers to indicate the visuals, this
   document users the same convention.

4. Bars (53%) Maps (16%) Circles (14%)
   Blocks (12%) Line Graphs (5%)
   Taxonomy
   The approximately 60 visuals produced for the 1900 Exposition fall
   into these categories: bar charts (30), maps (9), visuals with circular
   features (7), visuals using large blocks of color (8), and line graphs
   (3). The visuals also use bold primary colors and abstract forms prior
   to modernist movements developed later in the twentieth century.

   Bars
   The most prevalent type of visualization is bar charts. Some are conventional
   bar charts with labels on the left, using a single color, with the values
   sorted. Red tends to be the dominate color for this type, although
   other colors like gray, yellow and green are also used. In one case
   the bars echo the shape of its subject – the state of Georgia (plate
   19).
   There are three cases (plates 17, 26 and 62) where a bar is wrapped
   spanning 2-3 vertical lines.

   Plate 60
   [4]
   An unconventional use of bars is a “woven” pattern of two contrasting
   colors (indicating two cities, plate 23.). The weave is used in plate
   14 where the timeline is woven with the measure of literacy.
   Another bar chart type uses 1-3 vertical bars to describe proportion
   indicated by 2-3 solid colors (plates 13 and 50). In one case, plate
   60, the bar is tilted 45 degrees.

7. Plate 5 Plate 8 Plate 42
   Maps
   [5]
   The second most prevalent type of visual is the map; the majority
   of these use US state or Georgia county boundaries filled with color
   indicating some measure such as population distribution (plates
   2, 5, 6, and 8). The maps include colored legends with circles of
   color to denote the categories. The political outlines may also be
   labeled with other indicia such as arrows and measures. (plates 8,
   20) Two of the maps (plates 41, 42) use filled and outline shapes
   to compare the US with other countries.

   Plate 37 Plate 27 Plate 22
   Circles
   [6]
   Several charts use circular elements; notable are the spirals in plates
   11 and 25 (often highlighted when showing the Du Bois visuals).
   The spirals are used to indicate large measures; instead of stretching
   out the lines as in a conventional bar chart, the measures are rolled
   up in a spiral.
   Other uses of circles include conventional pie charts (plate 37), and
   the “fan” chart (plates 27). A novel “target chart” uses concentric
   circles with wedge-shaped pointers to the center.

   Blocks
   [7]
   Bold blocks of color are used in several charts, for example, area
   graphs in plates 51, 53, 54:
   Some visuals use geometric (rectangular, triangular, pyramidal)
   blocks (plates 57, 55, 61)

10. Plate 7 Plate 21
    Plate 40
    Graphs
    [8]
    Only three of the visuals use the traditional line chart. Two of the
    three use red grid lines (plates 7, 21). The line graphs have annotations,
    often with rotated text. Plate 7 in unusual: the usual convention
    of time on x-axis with values on the y axis is reversed.

11. Dimensions
    [9]
    As displayed in Paris exposition, the Du Bois visualizations were
    large format, 22x28 inch posters, mostly in portrait orientation. (exceptions
    are plates 30 and 31). To duplicate this layout, use a aspect ratio
    of approximately 0.78 (portrait) or 1.27 (landscape). For example
    setting your canvas to 1584x2016 pixels, at 72 pixels/inch, will duplicate
    the original canvas. Alternatively smaller sizes can be used preserving
    the aspect ratio.
    28 in.
    22 in.

12. Plate 1 title Plate 60 title
    Typography
    [10]
    Each visual includes a title: typically hand-lettered, sans-serif bold,
    centered all-caps with a period at the end. The titles may span 2-3
    lines and its size of typically 3%-4% if the overall width. In some
    a smaller serif font is used.
    To duplicate using modern tools, Public Sans [4] and Charter [5]
    may be used for sans-serif and serif fonts, respectively. Other choices
    are B52-ULC W00 [6] for titles and Vasarely-Light [7] for running
    text. The font DU BOIS [8] from Vocal Type was specifically designed
    to pay homage to the Du Bois visualizations

    Plate 5 legend
    Legends
    [11]
    Several visuals use colored legends (plate 2, plates 5-6, 37,38, 60).
    The legends usually use an outlined circle of color, (except for plate
    2), and may be horizontal or vertically oriented.

    Plate 21 annotation
    Plate 31 annotation
    Plate 40 annotation
    Annotations
    [12]
    Many visualizations include commentary and annotations, which
    are typically done in a lighter weight and color. All text is in ALL-CAPS.
    Annotations are also used to clarify the message of the visual display,
    (often using rotated text)

15. Colors
    [13]
    Bold solid colors are characteristic of the Du Bois style. To maintain
    consistency in your designs, here is a Du Bois-style color palette.
    Note the use of the Pan-African colors [9] (used 20 years before they
    were defined). Black, brown, and gold are used to indicate racial
    makeup in plates 1, 13, and 54. Plates 12, 50, and 51 use black to
    indicate slavery, and green for freedom.
