Group nodes without links

[Benkevych]

Can i somehow connect couple of nodes in 1 group but without visible links?

There's probably different ways to achieve that, depending on what your intention is.
If it's just a visual difference and you simply wish to hide certain links, you can do that by setting a fully transparent color on those links. Something like:

linkColor={link => shouldHideLink(link) ? 'rgba(0, 0, 0, 0)' : link.color}

If however you wish to group nodes in another manner than not by the link force (or by configuring the link force in a different way) you can manipulate the internals of the forces in play in the system using the d3Force method.

i`ve tried that, and my links appear just black instead of transparent...

Seems like it's ignoring the alpha part. Are you using rgba? Also, are you running the latest version of react-force-graph?

I don`t know what was the issue, but everything works fine after reinstalling package. Both was latest versions...
Thank you for your time)
