Is your feature request related to a problem? Please describe.
With new GraphPass, the minimum node size needs to be reduced. Nodes seem slightly larger with the new approach to node scaling (as discussed on this Pull Request. I've tested about thirty diagrams in sigma.js and I think changing the min node size from 3 to 1 would be ideal with this new approach.

Describe the solution you'd like
In graphs.js (in app/assets/javascripts), change:

        minNodeSize: 3,

to

        minNodeSize: 1,

This should not be done until new GraphPass is brought into production.

Additional context
I've been putting screenshots into the Slack channel, but for example:

Collection 10004

Figure 1: Original, minNodeSize of 3. Note that the clusters of nodes run together, making the mouse over too difficult.

Figure 2: Suggested solution, minNodeSize of 1. Note that clusters of nodes are more legible, making a mouse over easy as in Figure 3.

Figure 3: With mouse over

Collection 10371

Figure 1: Same as above, minNodeSize of 3

Figure 2: minNodeSize of 1, makes selecting nodes easier

Figure 3: minNodeSize of 1, able to navigate diagram
