## Follow the Money Sankey Diagram

The Visio Guy had another cool Sankey diagram on his blog last week. Credits go to Chris Webb of Woodland Trust, who created this using the line thickness option rather than pre-wired shapes.

The diagram has a left-to-right orientation and shows the different sources of money received by the trust. The types of funds (e.g. grants, legacies, direct marketing) are grouped together by colors. Flows have percentile values, rather than absolute ones. I am not sure what the boxes labeled “Sys” are, but the colors change. All flows merge into the box “Finance” which has a subgroup “Sales Ledger”.

The flow bands between most of the nodes have a nice soft curving. This is why some people do refer to Sankey diagrams as spaghetti diagrams.

If you are using Visio, you can download this diagram and look how it has been done. Nice work! I hope to see more of these Sankey diagrams done in Visio….

## VisioGuy invents Radial Sankey Diagrams

Chris the VisioGuy recently came up with Radial Sankey Diagrams. Although he didn’t seem to be sure if there is a “need for radially-oriented Sankey diagrams”, the commentators of his post immediately came up with ideas: use for rotating or radiating processes, cigarette rolling, recursive industrial processes, reinvestments, and so on… even stellar nuclear reactions were mentioned.

This is the ‘Everything Radial’ Circular Sankey Diagram

… and this is the ‘Tangential Fly-off’ Circular Sankey Diagram

One concern seems to be that the proportional arrow magnitude doesn’t work that well, since the human eye perceives the arrow area rather than thickness in such a circular Sankey diagram.

Thanks VisisoGuy for this contribution to the big basket of Sankey diagrams

## Visio Pre-Wired Sankey Diagram Shape

Visio Guy has been “messing around with … Sankey Diagram Shapes for Visio again — because [he] just couldn’t resist”. 😉

The result is a pre-wired Sankey diagram shape, in which five flows exit from a process box. The flows scale automatically according to the user input.

VG’s example is fun, showing cost of living and what money is being spent on. I just hope his food spendings don’t spread 60/40 on chips and coffee… 😀
