Fastest Sankey for Power BI — path tracing, loop safety, multi-mode input & large-data performance.
If you visualize multi-level flows in Power BI — customer journeys, revenue attribution, supply chains, or process diagrams — basic bar and line charts can't show how value moves between stages. ProSankey helps you turn flat tables into clear, interactive Sankey flow diagrams that reveal the full path from source to outcome.
Use ProSankey to map any multi-level flow without manual reshaping, trace a single customer journey from acquisition to conversion, identify where volume is lost or gained between stages, and present flow analytics in stakeholder meetings without leaving Power BI. For example, drop in four categorical columns from a flat table and ProSankey draws the entire flow automatically — no source-target reshaping or Power Query required.
Unlike simple Sankey visuals that crash on circular data or require manual edge lists, ProSankey is built for enterprise flow reporting: it supports three input modes (Path, Graph, Hybrid), detects and renders loops without breaking layout, traces full upstream and downstream paths on click, and scales to thousands of nodes and edges with sub-second rendering.
Key Features
- Multi-mode input - Path Mode binds N-level columns directly, Graph Mode accepts explicit Source → Target edges, and Hybrid Mode combines both, so you skip data preparation regardless of how your data is shaped.
- Loop-safe layout - detects circular flows and renders them as elegant back-edge arcs, so cyclic data such as funnel regressions, pipeline returns, or HR movements never break the diagram.
- Path-level click-to-trace - click any flow to highlight its full upstream and downstream path; everything else fades, so analysts can isolate a single journey in one click.
- Auto-bucket "Other" - collapses low-volume flows into a single "Other" node based on a configurable threshold, keeping diagrams readable when your data has a long tail.
- Temporal Graph mode - bind a Time column and ProSankey unfolds the same network across periods, so revisit patterns become forward-flowing journeys instead of overlapping cycles.
- Node and edge styling - assign per-category colors, patterns, borders, and opacities, and map a category column to distinct edge colors and dash styles to distinguish paid vs organic, hot vs cold, or any flow dimension.
- Flow and node labels - show value or percentage directly on flow paths and nodes (not just in tooltips), with configurable font, size, and minimum-width threshold so labels appear only where they fit.
- Diagnostics panel - surfaces topology counts, cycle detection, category conflicts, and actionable warnings, so data issues get caught in development, not in the board meeting.
- Up to 16 levels - bind up to 16 categorical columns as flow levels for deep multi-stage journeys.
- Power BI native experience - works with slicers, bookmarks, tooltips, cross-filtering, context menus, PDF and PNG export, dark theme, and high-contrast accessibility.
