Geospatial Network Visualizations using ggraph
Lorena Abad
Showcasing the possibilities of using ggraph with a layout that
understands geographical space positions via sf. These examples use
sfnetworks and my implementation of ggraph still under construction
before a PR is possible, and can be installed as:

Break Free from Plastic
The data used here comes from the Tidy Tuesday weekly data project. This is week 5 of 2021 were we analyzed data from the “Break Free from Plastic” initiative. Have a look at the final plot:
Here is a step by step guide on how to recreate it.
Airports in the U.S.

The fourth way of visualizing a graph on a map
In his very helpful
blogpost
Markus Neteler (@internaut) guides us through three different ways to
plot a spatial graph on a map. With the ggraph and sfnetworks
combination, we can add a fourth way!

Examples of what can be done with the sfnetworks package is shown
here, with all the figures created with ggraph and ggplot2!
