I want to produce a circular cladogram in R. I was trying out the ape package and could produce something like this:

plot(tree,'f', use.edge.length=F)

enter image description here

Now I am not really happy with how the edges look like here. I tried out the evolview webserver, which got me something like this, which looks much nicer, especially regarding the edges. enter image description here

Can anyone suggest other R packages or a different approach with the ape package, to get similar results to the evolview tree?

The two main differences that stand out to me are the size of the labels and the relative lengths of the edges.

Label size can be controlled using the cex graphical parameter (using par(), or as a parameter to plot()).

Uniform edge length can be added to the tree by replacing the $edge.length property with a vector of 1s:

par(cex = 0.8) # Shrink text
tree$edge.length <- rep_along(1, tree$edge.length)
plot(tree, 'f', use.edge.length = TRUE)
