Expanding and collapsing channels
To view, highlight, and modify data, channels can expand and
collapse in several ways. By default,
the size of all channels in a stream graph is set to only allow three datums to
be shown.
A channel with less than four datums cannot be expanded or
collapsed and therefore will not have an icon next to it.
