How To Make Geographic Map Visualizations In R
Written by Matt Dancho
This article is part of a R-Tips Weekly, a weekly video tutorial that shows you step-by-step how to do common R coding tasks.
If you are explaining data related to geography or just want to visualize by latitude / longitude location, you need to know
ggplot2 & the
tidyverse for making maps.
This tutorial will show you how to make a publication-quality visualization! Here are the links to get set up. 👇
SPECIAL ANNOUNCEMENT: ChatGPT for Data Scientists Workshop on December 13th
Inside the workshop I’ll share how I built a Machine Learning Powered Production Shiny App with
ChatGPT (extends this data analysis to an insane production app):

Learn how to make geospatial maps using the
ggplot2 package in my 10-minute YouTube video tutorial.
Working with Map Data
The first thing we need when creating a map is data that represents the latitude and longitude. We need to use a function called
map_data() to collect the data in the right structure for a
map_data() function to collect lat/long data for the entire World.
Plotting the Map Data with ggplot2
We can use the
coord_map() functions to plot the world.
Visualizing Republican Voting
So what can we do with Map Data +
ggplot2? How about visualizing how the US voted in 1976?!
We learned how to make geospatial maps with
ggplot2. Great work! But, there’s a lot more to becoming a data scientist.
If you’d like to become a data scientist (and have an awesome career, improve your quality of life, enjoy your job, and all the fun that comes along), then I can help with that.
