My submissions

Day 1 – Part-To-Whole

ggplot2 visual using pictorial percentage chart (see part-to-whole)

• Code: Day01.R
• Packages used: tidyverse (ggplot2), sf, patchwork, ggtext
• Data sources:
  • Wikipedia: Forest cover by state and territory in the United States; note: the official source is US Forest Service's Forest Inventory and Analysis.
  • Census States Shapefile (2018)
• Unrelated, but check out rFIA

Resources that helped:

• Adapted mostly from SO: Pictorial percentage chart in R
• Coordinate reference system (crs) explainer
• plot_annotation (patchwork)
• SO: color in patchwork title
• SO: bold/emphasis in annotate function

Day 2 - Waffle

ggplot2 waffle

• Code: Day02.R
• Packages used: tidyverse (ggplot2, plyr), rvest, janitor, patchwork, liamgilbey/ggwaffle
• Data sources: Wikipedia lists of single-movie box office gross revenues; ex. year of 1969
• Notes:
  • Legend output has a bug I couldn't work around.
  • Some months have 6 weeks (vs. usual 4-5 weeks) in length. This impacts the "ease" of looking at the visual.
  • Color choice could use some work.

Resources that helped:

• ggwaffle's docs
• SO: patchwork::wrap_plots explainer
• viridis palette generator
• patchwork's plot_layout doc
