Sankey Diagram Maker

About This Template

Sankey Diagram Maker is a Reflex template for building and editing a Sankey graph from your own data. A Sankey chart shows how quantities move between stages, while a proportional Sankey plot makes the largest flows easy to compare. This makes the visualization useful for energy, budget, traffic, conversion, and supply-chain analysis. The Sankey diagram generator opens with seeded scenarios, stages, nodes, links, totals, warnings, and palettes, so you can make a Sankey diagram immediately without credentials or setup. Edit nodes and links directly, and conservation checks flag any stage where inflow and outflow disagree. Keyboard selection keeps the Sankey graph accessible, while a contextual flow inspector explains the percentages behind each ribbon. An accessible link table mirrors the Sankey chart for screen readers and detailed data review. Scenarios can be saved, switched, and undone without losing the current flow data. For teams working in Python, the Reflex implementation provides an editable Sankey diagram in Python rather than a static image. Developers can use the Python Sankey chart as a starting point, then adapt its data model, interactions, labels, and responsive layout in code.
