Pat uses R to recreate the iconic fan plot figure that WEB DuBois presented at the 1900 Paris Exposition showing the difference in occupations of Blacks and whites using tools from the ggplot2, dplyr, and showtext packages. The functions he uses from these packages include aes, annotate, arrange, coord_equal, cos, cumsum, element_blank, element_rect, element_text, factor, filter, font_add, function, geom_point, geom_polygon, geom_text, ggplot, ggsave, labs, lag, library, map, margin, mutate, nest, paste, paste0, pivot_longer, scale_fill_manual, select, seq, showtext_auto, showtext_opts, sin, sum, theme, tibble, tribble, and unnest. You can find the data and code he developed in this episode at https://www.riffomonas.org/code_club/2025-02-17-panel-27. Pat's newsletter describing how he would go about generating a this figure can be found at https://shop.riffomonas.org/posts/making-pie-charts-for-my-biggest-fans. The book Pat mentions by Whitney Battle-Baptiste and Britt Rusert, titled "W.E.B. Du Bois's Data Portraits: Visualizing Black America" is available at https://amzn.to/4heJOWZ.
