I use dot, and manually position everything, then use the neato -n2 option to render:

`dot -T ${format} -n${n} ${verbose>1?"-v ":""}-Goverlap-true -Gsplines=false -Kneato -o "${ output }" "${ input }"`

this still doesn't do subgraphs well,

so I sometime do the 'groups' in a separate document, then composite the layers with image magick

`magick composite ${verbose>1?"-verbose ":""}-gravity NorthWest "${a}" "${b}" "${png_output}"`;

Not as easy to use, because it does not have a simple cli, but nested layouts are better than dot's with the Eclipse Layout Kernel. There is a JavaScript version, as well and you can try it in recent plantuml versions.

Also, this is a great problem, and we tried to solve it in a more general context. http://dpd.cs.princeton.edu/Papers/DGKN97.pdf

I believe it's an open problem what makes a curve look "natural" or how to do a good job of routing multiple splines around obstacles so they do not intersect each other, though the work of Keean Crane at CMU seems promising: https://www.cs.cmu.edu/~kmcrane/Projects/RepulsiveCurves/ind...
