arrows for edges?

[zktuong]

Hi, thanks for this really great package! I'm trying to incorporate the chord diagrams as a way to visualise cellular interactions.

So far it's great and i manage to create a plot that looks like:

I was wondering if there's a way to plot the edges as arrows intead of just lines at the moment?

Hey there, do we have any update on this possible enhancement? My group works with some circos plots that have a lot of lines and we are trying to figure out a way to make it easier to people see from where the data is from and where it is going in the plot.
Thanks!
