The sizes of the subgraphs can be set in two ways. The first way is to change the size of all the neurons by the command nsize. The parameter <value> means the perceptual size of the basic size which is computed based on the grid of the SOM. The second way is to use the diameters of the circles described in Section 7.3.4.
Example (ex7.13): The size of the neurons is set to 0.5 which means that it is half of the original size in the SOM's grid.
