class_docstr: CompositePlot provides a baseclass for plots coordinate multiple
  subplots to form a Layout.
code: def update_frame(self, key, ranges=None):
      ranges = self.compute_ranges(self.layout, key, ranges)
      for subplot in self.subplots.values():
          subplot.update_frame(key, ranges=ranges)
      self._update_title(key)
