Flowing Insight: Unveiling the Secrets of Sankey Mastery

Sankey diagrams, named after their inventor, English engineer William Playfair, are highly specialized and visually stunning tools for depicting the flow of materials, energy, or cost in processes. Despite their age (they were first introduced in the late 19th century), Sankey diagrams have endured as effective communication tools that are still widely used today across various fields such as engineering, environmental management, and financial analysis. This article delves into the creation of Sankey diagrams using modern techniques and their diverse applications.

The Essence of a Sankey Diagram

A Sankey diagram is constructed from a set of parallel horizontal lines (or “pipes”) that typically represent channels for flow. The width of these pipes grows with the amount being conveyed to reflect changes in flow rates. The direction of flow is shown by arrows with their lengths proportional to the quantity or throughput they represent.

Key Components:

Flow Lines: Representing flows with varying widths based on volume.
Nodes: Points where flows meet or split.
Arrows: Show directionality; longer arrows indicate higher flows.
Labels: Often include units of measure or descriptions to communicate clearly.

Sankeys have a knack for making complex data more comprehensible because they help us visualize differences between quantities in an intuitive way and are capable of illustrating energy losses through systems efficiently.

Crafting Your Sankey: The Art & Science

Creating an effective Sankey diagram involves both artistic sensibility and technical precision:

Steps to Create a Sankey Diagram:

Choose an Appropriate Tool: There are various software solutions for creating Sankeys; options range from free online tools like Sankey Flow and sankeys.js to professional packages like Microsoft Visio.
Identify Your Inputs & Outputs: Outline your system’s inputs, processes (nodes), and outputs clearly.
Quantify Flows: Gather data on what volume goes into each section that contributes to your output.
Create Nodes & Lines: Set up nodes at critical points where flow enters or leaves; create flowing lines between them proportional to the amount passing through each segment.
Add Arrows & Label Lines: Ensure each line has arrows showing directionality and labels indicating type or name where necessary.
Refine Aesthetics & Layout: Balance line widths visually while maintaining readability; ensure nodes are logically arranged without overlapping excessively.
Review & Refine until it Makes Sense – Test how well non-experts understand your diagram without needing additional explanations; refine accordingly until clarity is achieved.
Export & Integrate – Once you’re satisfied with your diagram’s accuracy and readability, export it in an appropriate format for use on digital platforms, print materials, presentations etc., according to intended use cases.
