Non rounded, horizontally aligned is it possible?

[azurda]

I am trying to achieve something like this with this component, is it possible? WHen adding lots of elements I end up with overlapping nodes (crossing each other) because of straight lines

I think it may be possible, by overriding how links are drawn.
Here's an example:

If you have an online example, let me know. I can try to take a quick look.

Just to understand your issue a little bit better, you want the links to appear as straight lines, right?
