Steve from wikibudgets.org posted a comment calling attention to a new free web app they have launched on their website.
This is a straight-forward drawing tool for simple left-to-right distribution diagrams. On the website just pick a node (called “budget” there) and an arrow (called “transfer”), add amount, choose color. The elements can be dragged freely in the browser window. Easy zooming with mouse wheel or double-click on an element. The ‘Save Image’ command from the browser’s context menu lets you store a PNG file.
The motto of wikibudgets.org is to “Visualise public budgets. Rationalise politics. Tackle Corruption. Eliminate waste. Fight bureaucracy.” The Sankey diagrams everyone can produce with this tool aim at visualizing financial transfers in US$.
According to the wikibudgets.org blog this is a first early release of the open source Sankey app for desktop UI. Touch friendly editing for mobile devices is under development.
Added to the list of Sankey software.
