+The iterations of layout, which is used to iteratively optimize the position of the nodes and edges in the Sankey diagram to reduce the overlapping between nodes and edges. The default value is `32`. If you want the order of the nodes in the chart to be the same with the order in the original [data](~series-sankey.data), you can set the value to be `0`.
