docstr: Assigns extra meta information associated with this trace that
  can be used in various text attributes. Attributes such as
  trace `name`, graph, axis and colorbar `title.text`, annotation
  `text` `rangeselector`, `updatemenues` and `sliders` `label`
  text all support `meta`. To access the trace `meta` values in
  an attribute in the same trace, simply use `%{meta[i]}` where
  `i` is the index or key of the `meta` item in question. To
  access trace `meta` in layout attributes, use
  `%{data[n[.meta[i]}` where `i` is the index or key of the
  `meta` and `n` is the trace index.
  
  The 'meta' property accepts values of any type
  
  Returns
