Found this breakup Sankey on Cliff Kuang’s blog, originally created and posted by Lee Byron.

Another very creative use of Sankey diagrams to show how couples split up. No absolute data given, and no percentages either, it is basically a decision graph with Sankey arrows. Some percentages given in the annotations.

Reminded me of this Sankey diagram for focussing on a societal topic.

Has the designer Lee Byron been inspired by his famous namesake’s poem?

When we two parted
In silence and tears,
Half broken-hearted
To sever the years,
Pale grew thy cheek and cold,
Colder, thy kiss;
Truly that hour foretold
Sorrow to this.

The majority of Sankey diagrams I have come across so far show energy flow systems (see this post or this one) and material flow systems (my last post or this one). To a lesser extent the examples found on the web show flows of materials in process systems (e.g. a plant).

To show the number of people that have been accused of abuse of detainees in a Sankey diagram is a novel idea. The example below, originally published by the New York Times (and posted by Derek Cotter on Edward Tufte’s board ‘Ask E.T.’) features the distribution of the 600 cases and what the different outcomes were.

The poster of the comment does criticize the inadequate diagram and says that “it might as well have been a pie chart instead”, however, the use of a Sankey diagram does give a kind of time line or at least a line of the decisions taken in the juridical system.

Choosing gray as the color rather than making it a colorful Sankey does reflect the topic adequately, I think.

Guilty of Sankey abuse? Or acquitted?
