Data #!N #!EC #!N #!N This example describes a regular 2-dimensional 
grid. In this example, unlike other examples presented here, the data 
are dependent on (in a one-to-one correspondence with) the "connections" rather 
than the "positions" component. Data Explorer interprets this as implying that 
the data value within each connection element is the constant given 
by the corresponding data value. For example, if you used AutoColor 
and rendered this Field, you would see blocks of constant color.
