              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.

              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}". 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:
                  %{2019-01-01|%A}".

                  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 `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>`.
