Zuil provides an alternative rendering of the Sankey diagram / flow chart. This one is surely superior, being easier to understand while capturing more information than the previous example.
Ultimately, however, this type of chart will please specialists more than the general reader.
It is designed to be purely descriptive, which explains the absolute equality given to each flow, as indicated by the choice of unique colors and/or patterns for each.
As a data graphic, it can be improved if the designer has a point to make. In that situation, only the relevant flows can be highlighted while all others stay in the background.
As it stands, this chart murmurs but does not opine.
