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 (and Animate) a Circular Time Series Plot in R
Also known as a polar plot, it is usually not the better option over a standard line chart, but in select cases the method can be useful to show cyclical patterns.
Detecting and Plotting Sequence Changes
Change detection for a time series can be tricky, but guess what, there’s an R package for that. Then show the results in a custom plot.
Interactive Time Series Chart with Filters
Time series charts can easily turn to spaghetti when you have multiple categories. By highlighting the ones of interest, you can direct focus and allow comparisons.
