Hello, I am wondering, what tool/R-package can be used to draw this type of tree (preferably, programmatically)?

The image is taken from: https://www.ncbi.nlm.nih.gov/pubmed/26773003
If you're handy with Python, then ETE Toolkit will do this and more.
You asked a similar question last week (https://www.biostars.org/p/217510/#217564), and my answer is the same. This looks to be a case of two different graphics combined. Check the differences in the fonts, for example.

The left part looks rather standard so no need for recommendations there, probably something like the right part could be made with https://github.com/griffithlab/GenVisR
You might take a look at facet_plot.
