-  it its data. Viewers are typically written to HTML files in order to be
-  displayed.

-  Python-side, a viewer class can be anything, as long as it implements the
-  WriteDataToFileAsJSON. The data written here is passed to the
-  data_binding_property of the JS-side class specified during the viewer's
