How to change edge connection points between nodes VisJs

I'm trying to code a visualization pipeline in VisJs. So I have a graph and some nodes. The nodes can generate/use a few different data types. So I need something like this

------------------
|     Node1      |
------------------
int           char
 |             |
 |             |
 |             |
 |             |
int  string   char
------------------
|     Node2      |
------------------

So one node has more than 1 anchor points that only connect to it's own type. Can I change the location from where the edges are drawn to where they are connected in the node? Does anyone know a better JS library to do this or can this be done with VisJs?
