As far as I know, all the layouts do optimize for something. The position
will not only depend on the node index but on the structure (minimize stress,
edge crossings, ...). Since the structure changes the node position changes.
To really fix the layout you could attach x and y attributes to your data and
map those attributes to the coordinates. Creating the coordinates of the
circular layout should be easy in any scripting language. Or you can use one
network as a template: Layout, use
`visualization > appearance to attribute > coordinates`, copy the attributes
to all networks, apply via `mapping > coordinates > cartesian`.
