Getting Started with Network Graphs in R
Add the vertices. Connect them with edges. Repeat as necessary.
Graph theory is an entire branch of mathematics, but it’s not too complicated to get started with drawing network graphs in R. The igraph R package, which is also available in Python and C, takes care a lot of the work, so that you can mostly focus on adding edges and vertices.

How to Make Slopegraphs in R
Also known as specialized or custom line charts. Figure out how to draw lines with the right spacing and pointed in the right direction, and you’ve got your slopegraphs.
How to Make a Semicircle Plot in R
It’s the half cousin of the bubble plot with less overlap and more straight edges.
How to Make Dot Density Maps in R
Choropleth maps are useful to show values for areas on a map, but they can be limited. In contrast, dot density maps are sometimes better for showing distributions within regions.
