Syntaks
Brukeren skriver først inn sankey -syntaksen, limer deretter inn rå CSV nedenfor, og får resultatet.
Men det er en liten forskjell fra standard CSV:
- CSV-en må inneholde bare 3 kolonner
- For det visuelle resultatet tillates tomme linjer uten kommaskilletegn
Grunnleggende
De 3 kolonnene i CSV-en representerer source , target og value .
