Sankey Chart

Sankey diagrams visualize flow and weighted relationships between categories.

Overview​

The Sankey chart shows how values flow from source to target, with the width of connections representing the volume or weight of interactions.

When to Use​

  • Visualizing communication flow between departments
  • Showing resource allocation across teams
  • Displaying process flows with quantities

Configuration​

Source & Target​

Select categorical columns (e.g., Department, Team, Region) for the left and right sides of the diagram.

Department Column​

Used for color-coding the flow bands.

Timeline Playback​

Like the network graph, Sankey charts support time-based animation when a date column is configured. Timeline playback respects the sidebar time range slider — animation only covers the selected date range.

Interpreting Results​

  • Wider bands: More interactions/higher values
  • Color coding: Identifies source category
  • Hover tooltips: Show exact counts
