title: How to use LookupTables in dash_vtk
body: <p>I am trying to find a way to use LookupTables for coloring a GeometryRepresentation in dash_vtk.
  The <a href="https://dash.plotly.com/vtk/representations" rel="nofollow noreferrer">documentation</a> states that there is an option &quot;useLookupTableScalarRange&quot; in the mapper of the GeometryRepresentation which is a boolean. But I can't find out how to setup a LUT and use it...
  Any ideas/experience?</p>
