              color
                  Sets the `link` color. It can be a single
                  value, or an array for specifying color for
                  each `link`. If `link.color` is omitted, then
                  by default, a translucent grey link will be
                  used.
              colorscales
                  A tuple of :class:`plotly.graph_objects.sankey.

                  compatible properties
              colorscaledefaults
                  When used in a template (as layout.template.dat
                  a.sankey.link.colorscaledefaults), sets the
                  default property values to use for elements of
                  sankey.link.colorscales

                  Assigns extra data to each link.
              customdatasrc

              hoverinfo
                  Determines which trace information appear when
                  hovering links. If `none` or `skip` are set, no
                  information is displayed upon hovering. But, if
                  `none` is set, click and hover events are still
                  fired.

                  Template string used for rendering the
                  information that appear on hover box. Note that
                  this will override `hoverinfo`. Variables are
                  inserted using %{variable}, for example "y:
                  %{y}". Numbers are formatted using d3-format's
                  syntax %{variable:d3-format}, for example
                  "Price: %{y:$.2f}".

                  for details on the formatting syntax. Dates are
                  formatted using d3-time-format's syntax
                  %{variable|d3-time-format}, for example "Day:

                  formatting syntax. The variables available in

                  variables `value` and `label`. Anything
                  contained in tag `<extra>` is displayed in the
                  secondary box, for example
                  "<extra>{fullData.name}</extra>". To hide the
                  secondary box completely, use an empty tag
                  `<extra></extra>`.
