Sankey diagrams

A Sankey diagram is a flow diagram in which the width of the arrows is proportional to the flow rate. There are many tools to draw them but they are graphical. This would make a great addition to plantuml as the diagrams are usually data driven.

Hello A.,

- Would that be enough?

@startuml
title Bracketed line thickness
node foo
foo --> bar                 : ∅
foo -[thickness=1]-> bar1   : [1]
foo -[thickness=2]-> bar2   : [2]
foo -[thickness=4]-> bar3   : [4]
foo -[thickness=8]-> bar4   : [8]
foo -[thickness=16]-> bar5  : [16]

If that can help,

As an addition, you could probably use a preprocessor macro to change "thickness" to "flow"

EX:

@startuml
!flow = "thickness"
title Bracketed line thickness
node foo
foo --> bar                 : ∅
foo -[flow=1]-> bar1   : [1]
foo -[flow=2]-> bar2   : [2]
foo -[flow=4]-> bar3   : [4]
foo -[flow=8]-> bar4   : [8]
foo -[flow=16]-> bar5  : [16]
