SankeyFlow turns a list of flows into a Sankey diagram — the chart that shows how a quantity splits and merges as it moves from one place to another. Budgets, energy use, website traffic, headcount, material flows: if it's a total that divides into parts, SankeyFlow draws it. THREE WAYS TO BUILD • Type it. One line per flow: Salary [3000] Budget, with a built-in guide to the syntax. • Build it visually. A drag-to-reorder list of source, amount, and target — rearrange rows to restack the diagram. • Import a spreadsheet. Paste from Excel or Numbers, or open a CSV or XLSX file. TUNE EVERY DETAIL Set the flow direction — left, right, up, or down. Adjust node width and spacing, ribbon curve and opacity. Give nodes their own colours from a hand-tuned palette. Show or hide names and values. Set a unit and a background. BALANCE THE BOOKS When a box receives more than it passes on, or less, SankeyFlow can show the difference as a Remainder box or send it to a box you choose. Set it for the whole chart or for individual boxes. EXPORT ANYWHERE Save to PNG, PDF, or SVG. Choose an aspect ratio or an exact pixel size, set a resolution, add margins — all with a live preview. The SVG output is clean and standards-compliant, ready for the web or further editing in a vector app. A REAL MAC APP Documents with autosave, a version history you can browse and restore from, and tabs for several charts at once. Full keyboard control. Light and dark. SankeyFlow runs entirely on your Mac — no account, no sign-in, no network. Nothing you make ever leaves your machine.
