              color
                  Sets the `node` color. It can be a single
                  value, or an array for specifying color for
                  each `node`. If `node.color` is omitted, then
                  the default `Plotly` color palette will be
                  cycled through to have a variety of colors.
                  These defaults are not fully opaque, to allow
                  some visibility of what is beneath the node.
