Set up node sizing
The default node size is dependent upon the number of connections the node has - the more connections, the larger the node and vice versa.
This can be changed by clicking on settings (the gear icon) in the Graph view at the bottom right corner of the page and selecting “Set up node sizing.”
Ignoring number of relationships
By changing all of the node settings to “(ignore),” you can program node size to ignore the number of relationships each has. This will result in all nodes being the same size.
Sizing by number column
If one of the node tables has a number column, such as population in this example, you can select that to be the determining factor of node size.
