Title: “Sankey’s Sketch: A Stroke-by-Stroke Guide to Visualizing Data with Sankey Charts”

Imagine a painter, Sankey, who had the magical ability to turn complex data into easy-to-understand visuals. This conjurer of charts, known worldwide as Sankey charts, transforms the mountains of data into a simple flow of information. Just as a stroke of his brush turns a blank canvas into a masterpiece, his charts make trends visible with a single glance.

What is it about Sankey charts that make them such powerful storytelling tools?

Sankey Charts: The Basics

Sankey diagrams were first developed by Irish engineer Matt Sankey in 1927. The central idea is to visualize the distribution of flows into and out of a system. The classic example would be showing the path energy takes through a cyclic process, with the width of each path proportionate to the amount of energy involved.

Step 1 – Defining the Source and Sink

At the very core of a Sankey chart, you’ll typically see two key regions: the source and the sink. This is where your data journey begins and ends. You may be looking at the total energy input compared to the energy output, the total cost of production versus sales, or digital data flow in and out of a system.

Step 2 – Mapping Data Flow Paths

Think of each path in your Sankey chart as a data story. Just as artists use their brush to build a composition, each arrow in your Sankey chart directs the reader’s eye along specific flows of information. The flow’s length signifies volume (in our energy example, the length would represent a higher volume of energy), while width indicates proportion (more significant flows get wider arrows).

Step 3 – Labeling the Flow Paths

Not unlike art where every color and line tells its part of the story, labeling is vital for a Sankey chart. Labeling each path tells the viewer what the data represents, creating a narrative of where each data slice contributes, and where it goes.

Step 4 – Adding a Complementary Color Palette

Just as the artist’s palette provides colors that enhance the emotion, a Sankey chart’s color scheme enhances clarity. Using a gradient of colors can help highlight the flow intensity visually and provide a harmonious balance of information on the chart.

Step 5 – Let It Tell the Story

Remember, the Sankey chart is an artist in its right. It combines data and aesthetics to tell a story. This storytelling doesn’t end when the last stroke is laid down. Effective communication is subjective, so always test your Sankey chart with the audience to ensure it conveys the intended message.

In industries ranging from physics and engineering to business and finance, Sankey charts have consistently been a favorite tool for data visualization. Now, with software making it easier to create custom Sankey charts for your unique datasets, there’s no reason why you can’t harness this power for your business, project, or personal data story.

With each stroke of your data brush, bring to life the hidden magic of energy and data, and allow the world to see and understand what Sankey is illustrating so beautifully.
