The simple (and inelegant) fix to your problem is to set the shape.node parameter to "none". This will remove the presence of any nodes while retaining the names. This may be sufficient for you. However, if you cannot identify the block by the feature name, it compounds your issue rather than solves it.
I’m currently working on an adjustment to the network() which should give you control of the size of each node as well as influence over the distance between them. I’ll update you once this is fully implemented
