This extension allows you to create Sankey diagrams—also known as flow diagrams or alluvial diagrams—from different types of categorical flow data. Sankey diagrams are one of the most effective ways to visualize connections, transitions, and proportional flows between different categories or stages in a process.

With this tool you can:

  • Load data in multiple ways: copy and paste into a blank table, upload files in formats such as CSV, Excel, or others, or use datasets already stored in your Datasketch library or publicly shared by other users.
  • Visualize complex flows intuitively: represent how quantities move, transform, or distribute between different categories, stages, or entities with proportional flow bands that make relationships immediately clear.
  • Track multi-stage processes: follow how items, people, money, or any measurable quantity transitions through multiple steps, revealing bottlenecks, losses, or concentration points in your data.
  • Edit the data table and instantly see changes reflected in the diagram: allowing you to adjust, clean, or reorganize flow information while observing its immediate impact on the visualization.
  • Customize colors, labels, and styles: adapt the diagram to your analytical context, brand colors, or presentation needs with professional color schemes that highlight important flows or categories.
  • Handle categorical data automatically: the extension intelligently processes your flow data and creates the appropriate node and link structure for optimal visualization.
  • Export and save diagrams in different formats: share them on social media, embed them in websites, or store them in your Datasketch library to keep a record, reuse them, or make them available to other users.

Perfect for displaying: customer journey flows, budget allocations, process workflows, migration patterns, energy flows, supply chain movements, conversion funnels, resource distributions, and any dataset where understanding connections and proportional flows between categories is crucial.
