Visualising tiered data can be problematic as it often consists of many levels, which may each also contain a high volume of items. This could result in an extremely wide chart that makes it difficult to gain any valuable insights from the high level structure.

The stacking option for sequential layout offers a solution. By setting its arrange property to 'grid', groups of four or more nodes with identical connections are stacked to significantly reduce the amount of space required to display the full chart width.

For data visualised as multiple disconnected components sequential can pack the individual components using any available packing option.
