Is it possible to pass options to the layout engine ?

[kasra0]

Hi,

I need to pass the -n2 option to neato.
I tried something like

$ dot-wasm -K neato -n2 pack.dot > out.svg
But I don't have the right result.

With graphviz I have this command :

$ neato -n2 pack.dot -Tsvg > out.svg

that gives :

If I don't pass the n2 option I have the wrong result ( same as dot-wasm -K neato -n2 pack.dot > out.svg)
$ neato pack.dot -Tsvg > out.svg

the input file:
pack.txt

thanks

@kasra0 looks like its currently not supported in the command line interface (but is supported in the JavaScript API), I will add it.

@GordonSmith Could you please clarity how it is possible to pass the -n2 option to the neato layout engine via the JavaScript API? I couldn't find anything about that in the documentation. Thanks!

Answering my own question for those who this may come up for, the 'nop' options seems to control the -n flag, so -n2 would be { nop: 2 }. This was a useful forum discussion of the 'n' option as well:
