Water flows in AmsterdamBack to list
This sankey diagram illustrates the water flows in Amsterdam. It makes the importance of each of the flows immediately clear. There is one confusing aspect to this diagram: the patterns used (horizontal lines, diagonal lines, etc.) are not explained in a legend and seem to have no particular use (if you look closely, each pattern is unique and does not repeat itself). Ideally, patterns should be used to mark a particular characteristic of the flow.
