#30DayMapChallenge is an initiative started on Twitter by Topi Tjukanov. The aim of the challenge is to create a map each day of the month on a given theme. Below are some of my contributions to the challenge. I usually choose whatever tool is appropriate for the vizualization task, but for this challenge I limited myself only to using ggplot2 so I can learn more about its mapping capabilities.
Day 1: Points
Day 2: Lines
Day 3: Polygons
Day 4: Hexagons
Day 5: Raster
Day 6: Blue
Day 7: Red
Day 8: Green
Day 9: Yellow
Day 10: Black and White
