docstr: Construct a new Marker object
  
  Parameters
  ----------
  arg
      dict of properties compatible with this constructor or
      an instance of
      :class:`plotly.graph_objs.scattermapbox.Marker`
  allowoverlap
      Flag to draw all symbols, even if they overlap.
  angle
      Sets the marker orientation from true North, in degrees
      clockwise. When using the "auto" default, no rotation
      would be applied in perspective views which is
      different from using a zero angle.
  anglesrc
      Sets the source reference on Chart Studio Cloud for
      angle .
  autocolorscale
      Determines whether the colorscale is a default palette
      (`autocolorscale: true`) or the palette determined by
      `marker.colorscale`. Has an effect only if in
      `marker.color`is set to a numerical array. In case
      `colorscale` is unspecified or `autocolorscale` is
      true, the default  palette will be chosen according to
      whether numbers in the `color` array are all positive,
      all negative or mixed.
  cauto
      Determines whether or not the color domain is computed
      with respect to the input data (here in `marker.color`)
      or the bounds set in `marker.cmin` and `marker.cmax`
      Has an effect only if in `marker.color`is set to a
      numerical array. Defaults to `false` when `marker.cmin`
      and `marker.cmax` are set by the user.
  cmax
      Sets the upper bound of the color domain. Has an effect
      only if in `marker.color`is set to a numerical array.
      Value should have the same units as in `marker.color`
      and if set, `marker.cmin` must be set as well.
  cmid
      Sets the mid-point of the color domain by scaling
      `marker.cmin` and/or `marker.cmax` to be equidistant to
      this point. Has an effect only if in `marker.color`is
      set to a numerical array. Value should have the same
      units as in `marker.color`. Has no effect when
      `marker.cauto` is `false`.
  cmin
      Sets the lower bound of the color domain. Has an effect
      only if in `marker.color`is set to a numerical array.
      Value should have the same units as in `marker.color`
      and if set, `marker.cmax` must be set as well.
  color
      Sets themarkercolor. It accepts either a specific color
      or an array of numbers that are mapped to the
      colorscale relative to the max and min values of the
      array or relative to `marker.cmin` and `marker.cmax` if
      set.
  coloraxis
      Sets a reference to a shared color axis. References to
      these shared color axes are "coloraxis", "coloraxis2",
      "coloraxis3", etc. Settings for these shared color axes
      are set in the layout, under `layout.coloraxis`,
      `layout.coloraxis2`, etc. Note that multiple color
      scales can be linked to the same color axis.
  colorbar
      :class:`plotly.graph_objects.scattermapbox.marker.Color
      Bar` instance or dict with compatible properties
  colorscale
      Sets the colorscale. Has an effect only if in
      `marker.color`is set to a numerical array. The
      colorscale must be an array containing arrays mapping a
      normalized value to an rgb, rgba, hex, hsl, hsv, or
      named color string. At minimum, a mapping for the
      lowest (0) and highest (1) values are required. For
      example, `[[0, 'rgb(0,0,255)'], [1, 'rgb(255,0,0)']]`.
      To control the bounds of the colorscale in color space,
      use`marker.cmin` and `marker.cmax`. Alternatively,
      `colorscale` may be a palette name string of the
      following list: Greys,YlGnBu,Greens,YlOrRd,Bluered,RdBu
      ,Reds,Blues,Picnic,Rainbow,Portland,Jet,Hot,Blackbody,E
      arth,Electric,Viridis,Cividis.
  colorsrc
      Sets the source reference on Chart Studio Cloud for
      color .
  opacity
      Sets the marker opacity.
  opacitysrc
      Sets the source reference on Chart Studio Cloud for
      opacity .
  reversescale
      Reverses the color mapping if true. Has an effect only
      if in `marker.color`is set to a numerical array. If
      true, `marker.cmin` will correspond to the last color
      in the array and `marker.cmax` will correspond to the
      first color.
  showscale
      Determines whether or not a colorbar is displayed for
      this trace. Has an effect only if in `marker.color`is
      set to a numerical array.
  size
      Sets the marker size (in px).
  sizemin
      Has an effect only if `marker.size` is set to a
      numerical array. Sets the minimum size (in px) of the
      rendered marker points.
  sizemode
      Has an effect only if `marker.size` is set to a
      numerical array. Sets the rule for which the data in
      `size` is converted to pixels.
  sizeref
      Has an effect only if `marker.size` is set to a
      numerical array. Sets the scale factor used to
      determine the rendered size of marker points. Use with
      `sizemin` and `sizemode`.
  sizesrc
      Sets the source reference on Chart Studio Cloud for
      size .
  symbol
      Sets the marker symbol. Full list:
      https://www.mapbox.com/maki-icons/ Note that the array
      `marker.color` and `marker.size` are only available for
      "circle" symbols.
  symbolsrc
      Sets the source reference on Chart Studio Cloud for
      symbol .
