Add the possibility to link a node to itself

[simonefranza]

Hi,

first thanks for the framework it really works great!

Do you think it would be possible to add links from a node to itself (i.e. a link with tid === sid)
so that it would be visible? As of now you can of course add that link but it isn't drawn

That would be really cool!

Hi @simonefranza, thanks for your comments!
Why do you want to link a node to itself? What kind of visualization do you imagine for that?

I'm drawing a graph given an adjacency matrix (see here). The values on the diagonal represent links to itself, so as of now they have to be 0, but since the matrix is interactive, it would be cool if one could also edit the diagonal of the matrix and it would get reflected on the graph
