We only add to nodes that are big enough to fit the text. As we don't know how big the text would be (it can be changed via CSS), we use a rough estimate. openspending/openspending#1199

D 3.5 of WP3 OBEU had as its aim to give recommendations on how the different visualization types could be enhanced so that they meet best best practice requirements in data visualization. J++ was in charge of this report that is publicly available:
http://openbudgets.eu/assets/deliverables/D3.5.pdf
The following recommendations can be found in the report:
Sankey diagram
The use of payer/beneficiary (to compare two different hierarchies/dimensions)
The sankey visualisation can be useful to visualise who is giving and who is getting money.
This type of visualisation has been developed in one of the tools developed in Work Package 5 to display which professional football club received money from which public body and in which proportion.
Display the total amount of a node
The root of the links can be used to display the amount of money represented by a node.
Display the numbers in the legible way
To increase the legibility, the numbers can be displayed in a human-friendly way in changing the precision of the amounts. A value “11,069.15” can be better understood as “11K€”.
Display the currency
To add the context, the currency of the amount displayed should be always visible to the reader.
