docs: Computes and adjoins histogram along specified dimension(s).
  
          Defaults to first value dimension if present otherwise falls
          back to first key dimension.
  
          Args:
              dimension: Dimension(s) to compute histogram on
              num_bins (int, optional): Number of bins
              bin_range (tuple optional): Lower and upper bounds of bins
              adjoin (bool, optional): Whether to adjoin histogram
  
          Returns:
              AdjointLayout of DynamicMap and adjoined histogram if
              adjoin=True, otherwise just the histogram
