I was wondering is it possible to visualize tree structure, in particular the branch nodes are shown.

The example is from wikipedia (https://en.wikipedia.org/wiki/Newick_format) and tree in the newick format is: (A:0.1,B:0.2,(C:0.3,D:0.4)E:0.5)F;

I can visualize tree by ggtree, but I did not know which parameters can highlight the branch nodes.

v <- '(A:0.1,B:0.2,(C:0.3,D:0.4)E:0.5)F;'

ggtree(read.tree(text=v)) + geom_tiplab() 

My motivation of using ggtree is to visualize lineage tree, e.g. C.elegans, thus I care more about branching nodes (e.g. E and F in the example) and their child nodes.

Thanks,

root = 5
ggtree(read.tree(text=v)) + geom_point() + geom_text(aes(label=label), hjust=-.5) + geom_label2(aes(x=branch, label=branch.length, subset=(node != root))) -> p
rotate(p, root)

ggtree(read.tree(text=v)) + geom_point() + geom_text(aes(label=label), hjust=-.5)

the above code should work.
