In this thread I'll show you the original plates for the #DuBoisChallenge

The first # #DuBoisChallenge plate: "Comparative Increase of White and Colored Population in Georgia" . It looks like a simple line chart with two sets of data, but notice how the axes are switched from today's conventions

The second plate for the #DuBoisChallenge: "Conjugal Condition": A set of grouped stacked proportional bars comparing the marital status of two populations. Note the color palette. (crimson, gold, green)

The third plate for the #DuboisChallenge: "Occupations of Negroes and Whites in Georgia": Not quite an piechart, but a "wedge chart" comparing the occupations of two groups. The colors from the previous plate are here as well:

The fourth visualization for #DuboisChallenge" has been seen in other venues like the series from @Jasonforrestftw "Proportion of Freeman and Slaves Among American Negroes". It's a "block" style using only two colors to represent slavery and freedom

The next visual for the #DuBoisChallenge : "Income and Expenditure of 150 Negro Families in Atlanta, GA, USA". Using a series of proportional bars combined with photographs, it describes how a various socioeconomic groups spends their income (rent, food, clothes, taxes, other)

Next on the #DuboisChallenge list is one of the famous Dubois spiral charts "City and Rural Population 1890"

Another one of the Dubois spiral charts for the #DuboisChallenge "Assessed Value of Household and Kitchen Furniture Owned by Georgia Negroes." rolls up data from 1875 to 1899.

As a bonus, the #DuboisChallenge also includes some map-based visualizations:

"The Georgia Negro. A Social Study by W.E.Burghardt Du Bois" served as a sort of title page for the exhibition, and depicts the slave trade routes from Africa to North and South America #DuboisChallenge

This map: "Migration of Negroes" shows the movement of people in the United States #DuBoisChallenge

The final visual for the #DuboisChallenge is a choropleth map of showing the population of freed enslaved people in 1890
