Unleashing the Power of Flow: A Guide to Mastering Sankey Charts

Sankey charts are more than just a visual tool for depicting flows. They are a potent means of illuminating complex data relationships and patterns without sacrificing clarity. If you’re looking for a way to bring your data to life, learn how to master the art of creating Sankey charts.

What Are Sankey Charts?

Sankey diagrams are a type of flow diagram that allows you to visualize how quantities are distributed or transferred from one point to another. They are particularly useful for visualizing flows of resources and material movements within a system, such as energy, economics, logistics, and more.

The fundamental elements of a Sankey diagram include:

  • Nodes: These represent the source, destination, or intermediate points in the flow.
  • Flow Lines: These are the arrows or bands that convey the magnitude and direction of the flow. The width of the lines reflects the magnitude of the flow between points.
  • Labels: These provide specific data about the flows, including the amounts moving between points.

How to Master Sankey Charts: A Step-by-Step Guide

1. Understand the Data Flow

Analytic and qualitative data is the backbone of Sankey charts. Start by defining the sources, purposes of the flow, and destinations to fully understand what you’re visualizing.

2. Select the Right Software

Different software platforms offer various levels of customization and complexity for Sankey charts. Tools like Microsoft Excel, Tableau, Google Sheets, and specialized software like DrawSankey.org provide basic to advanced features. Choose one that best suits your needs based on complexity and the depth of customization you require.

3. Prepare Your Data

Before creating the chart, organize your data into a suitable format. Typically, this involves setting up columns for:

  • Source: The starting point of the flow.
  • Destination: The endpoint of the flow.
  • Volume: The quantity being transferred from the source to the destination.
  • Name Tag: Optional elements for labeling components.

4. Create the Chart

Using Microsoft Excel:

  • Input your data into multiple columns.
  • Select the data, go to the ‘Insert’ menu, then choose the Sankey diagram chart type.
  • You might need to customize the node labels, edge widths, and colors for clarity.

Using Tableau:

  • Load your data into Tableau.
  • Drag your categories (source and destination) and volume metric to the respective sections (source/destination, columns, and rows).
  • Once the chart is generated, use the ‘Marks’ panel to adjust the nodes’ size, color, and flow line widths.

Using DrawSankey.org:

  • Create an account and log in.
  • Upload your data file.
  • Select elements (nodes and flows) and customize properties according to your needs.
  • Generate and adjust your chart as you finalize the elements.

5. Customize for Clarity and Impact

Sankey charts are as effective as they are functional, but with careful customization, you can enhance their impact:

  • Color Coding: Use distinct colors to differentiate between types of flows or to highlight key components.
  • Node Labels: Make sure to label nodes clearly to avoid confusion.
  • Legend: Provide a legend explaining the color scheme or categorization.
  • Edge Smoothness: Adjust the width and smoothness of the flow lines to indicate the magnitude of the flows and their relative importance.

6. Review and Refine

It’s crucial to review your Sankey chart for potential areas of confusion or undercommunication. Make sure the diagram flows logically and that the viewer can easily understand the flow of data.

Applications of Sankey Charts

Sankey charts find utility across numerous industries:

  • Economics and Finance: To illustrate how funds are allocated in processes like financial systems or spending across different sectors.
  • Environmental Science: To depict environmental flows, resource extraction and usage, or pollution routes.
  • Engineering and Energy: For visualizing power generation and distribution networks, or the composition of energy sources.
  • Healthcare: To depict patient flows in hospitals, resources used in treatments, or the flow of information in disease models.

Conclusion

Mastering the creation of Sankey charts is to take the pulse of your data and bring it to full life through visualization. With detailed data preparation, proper tool selection, and customized design, your Sankey diagram can become an invaluable tool for communication, decision-making, and process optimization. Remember, the key to a successful Sankey chart is in its clarity, informativeness, and the ability to convey complex data relationships in an easily understandable manner.
