ApexSankey
One flow model, several ways to read it
Sankey, alluvial and chord from the same nodes and edges. Animated updates, click-to-isolate paths, themes, plugins, and a before/after comparison view with a structural diff.
Works with
Animated data updates
Hand the diagram a new dataset and it transitions instead of redrawing. Same topology with different values, and nodes and ribbons spring to their new places. Different topology, and it morphs through the change: entering flows unfurl out of their source node, survivors slide, removed flows retract and dissolve.
Chord for many-to-many flows
A layered Sankey falls apart when everything connects to everything: ranks stop meaning anything and the ribbons cross into noise. Switch one option and the same nodes and edges draw as a ring, with each arc sized by everything entering and leaving it. Right for transfers, migration and traffic between peers.
Alluvial from categorical records
Cohort flow does not arrive as nodes and edges. It arrives as a table of subjects and their category at each step. Pass the dimensions and the records and the builder folds them into the flow graph, with axis titles per rank and a consistent colour per category so a single cohort is followable straight across.
Compare two states side by side
An animation shows that something changed. It is poor at showing exactly what. The comparison view renders a before and an after together and outlines every flow by how it changed: added, removed, or a different value. Hovering a node highlights its twin in the other panel, and the computed diff is available to drive your own summary.
Trace a path through the noise
Hover a node or a link and its connected upstream and downstream path stays lit while everything unrelated dims. Click instead and the path pins, so it stays isolated while you read it or point at it. Cycle-guarded, so a diagram with feedback loops terminates rather than walking forever.
Gradient blend mode
Blend each ribbon from its source colour to its target colour so a flow reads as a handoff between two things rather than a band of one colour. Drag the handle to wipe between blended and solid edges on the same diagram.
Built-in Themes
Five coordinated presets, or register a brand palette once and name it everywhere.
Particle Flow
Optional particles drift along each ribbon, denser where the flow is heavier.
Plugins & Events
A typed event bus plus built-in path tracing, time playback and drill-down.
Export
Download your diagram as PNG or SVG to drop into any document.
