docstr: The nodes of the Sankey plot.
  
  The 'node' property is an instance of Node
  that may be specified as:
    - An instance of :class:`plotly.graph_objs.sankey.Node`
    - A dict of string/value properties that will be passed
      to the Node constructor
  
      Supported dict properties:
  
          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.
          colorsrc
              Sets the source reference on Chart Studio Cloud
              for `color`.
          customdata
              Assigns extra data to each node.
          customdatasrc
              Sets the source reference on Chart Studio Cloud
              for `customdata`.
          groups
              Groups of nodes. Each group is defined by an
              array with the indices of the nodes it
              contains. Multiple groups can be specified.
          hoverinfo
              Determines which trace information appear when
              hovering nodes. If `none` or `skip` are set, no
              information is displayed upon hovering. But, if
              `none` is set, click and hover events are still
              fired.
          hoverlabel
              :class:`plotly.graph_objects.sankey.node.Hoverl
              abel` instance or dict with compatible
              properties
          hovertemplate
              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}" as well as %{xother}, {%_xother},
              {%_xother_}, {%xother_}. When showing info for
              several points, "xother" will be added to those
              with different x positions from the first
              point. An underscore before or after
              "(x|y)other" will add a space on that side,
              only when this field is shown. Numbers are
              formatted using d3-format's syntax
              %{variable:d3-format}, for example "Price:
              %{y:$.2f}". https://github.com/d3/d3-
              format/tree/v1.4.5#d3-format for details on the
              formatting syntax. Dates are formatted using
              d3-time-format's syntax %{variable|d3-time-
              format}, for example "Day: %{2019-01-01|%A}".
              https://github.com/d3/d3-time-
              format/tree/v2.2.3#locale_format for details on
              the date formatting syntax. The variables
              available in `hovertemplate` are the ones
              emitted as event data described at this link
              https://plotly.com/javascript/plotlyjs-
              events/#event-data. Additionally, every
              attributes that can be specified per-point (the
              ones that are `arrayOk: true`) are available.
              Variables `sourceLinks` and `targetLinks` are
              arrays of link objects.Finally, the template
              string has access to 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>`.
          hovertemplatesrc
              Sets the source reference on Chart Studio Cloud
              for `hovertemplate`.
          label
              The shown name of the node.
          labelsrc
              Sets the source reference on Chart Studio Cloud
              for `label`.
          line
              :class:`plotly.graph_objects.sankey.node.Line`
              instance or dict with compatible properties
          pad
              Sets the padding (in px) between the `nodes`.
          thickness
              Sets the thickness (in px) of the `nodes`.
          x
              The normalized horizontal position of the node.
          xsrc
              Sets the source reference on Chart Studio Cloud
              for `x`.
          y
              The normalized vertical position of the node.
          ysrc
              Sets the source reference on Chart Studio Cloud
              for `y`.
