Alluvial

The Alluvial Chart (also known as a Sankey Diagram) visualizes flows and relationships between different categories or stages.
It represents nodes (categories) and weighted links (flows) between them, making it ideal for illustrating how values split, combine, or transition through a system.

Use cases:

  • Displaying process flows or movement between stages.
  • Visualizing distribution of values across multiple categories.
  • Mapping data pathways or transfers in a system.

⚙️ Setup

  1. Drag the Alluvial Chart widget from the chart library onto your designer workspace.
  2. Select the chart.
  3. Go to the Widget Configuration tab in the Configuration panel.
  4. Under the Configuration panel tab, select the Basic Configuration option to access essential settings for the Alluvial Chart.
  5. Select the Source from which the chart will fetch its data.
  6. Map:
    • Measure — Numeric value representing the flow quantity between nodes.
    • Dimension — Sequential categorical values representing stages or nodes. Minimum of 2 dimensions required.
  7. Optionally add a Date field for time-based filtering.
