Your SankeyMATIC text, upgraded
SankeyMATIC is a great way to make a quick static Sankey. OpenSankey reads the exact same
source [value] target syntax — colors, node settings and layout included — and
gives you an interactive diagram you can keep editing.

How the import works
Open the editor, switch the spreadsheet panel to text mode, and paste. We parse the full
SankeyMATIC dialect: flows, :Node #color lines, comments, and the settings
block. You can keep working in text or switch to the visual editor at any point — both
stay in sync.
