Flow Visualizing Fun: Unveiling Secrets with Sankey Sauce
In a world dominated by ever-more complex systems and data, the ability to translate intricate processes into simple, digestible visualizations is crucial. Among the lesser-known visualization tools that serve this purpose effectively is the Sankey diagram, commonly affectionately referred to by some as “Sankey Sauce.” This article delves into the thrilling world of Sankey charts, exploring not just how they’re created but also the delightful applications they find in various fields.
Discovering the Sankey Diagram
A Sankey diagram is a specialized type of flow diagram where the width of connections (or vectors) between nodes is proportional to the quantity of flow contained in the connection. This distinctive scaling is perfect for illustrating energy transfer, material flow, or information. Unlike more commonly seen bar or pie charts, their unique design makes it easy to understand how mass or energy is distributed across a process.
The Sankey diagram was conceptualized by English engineer Dr. Martin Sankey in the late 19th century, originally used to visualize the efficiency of energy conversion in industrial processes. Since then, these visual masterpieces have evolved and found their way into numerous analytical tools and educational resources.
Crafting Your Sankey Sauce
Creating a Sankey diagram might seem daunting at first glance, but it need not be. Here is a simplified guide to help anyone become a Sankey wizard:
1. Identifying Your Sankey Dimensions
Before anything else, define the two axes – the left-hand vertical axis and the horizontal axis at the bottom. Nodes (data points) flow from the left to the right. Decide what these axes will represent – for instance, temperature or amount of material – and label them appropriately.
2. Flow Representation
Next, identify your nodes and the flows between them. Represent the flows with arrows – width of the arrows are scaled to reflect the flow magnitude. The sum of all the arrows entering a node equals the flow out of the node.
3. Creating Boxes and Pathways
The vector diagrams consist of several boxes (typically one for each process or element of a larger process) connected by arrows (pathways). Carefully design these boxes to be contiguous without gaps that could misrepresent the process flows.
4. Scaling Arrows
This is the heart of the Sankey sauce. Scale your arrows proportionally to the flow they represent. Larger flows will take up more of the diagram space.
5. Assembling & Adjusting
Once the base elements are in place, you can start assembling the chart. Look for ways to optimize the space and maintain clarity. You might need to adjust some arrows or boxes for a cleaner presentation without obscuring the flows.
6. Final Touches & Validation
Give your Sankey diagram a good review. Look for any inconsistencies, and be sure it accurately reflects the process you intend to describe. It’s not just about being correct, but also about clarity and legibility.
Sankey Sauce Applications
Sankey diagrams are not just visual feast for analytics enthusiasts; they have a myriad of practical applications across various fields:
1. Environmental Science
From studying global water cycles to analyzing energy consumption, Sankey diagrams can paint a clear picture of environmental systems and their flow of resources.
2. Renewable Energy
They are vital for showcasing the efficiency and energy flows in renewable energy systems, helping to optimize design and improve conversion rates.
3. Logistics
In logistics, Sankey diagrams can demonstrate efficiency and visualize the flow of goods or services through a supply chain, identifying bottlenecks where improvements can be made.
4. Finance
Finance practitioners use Sankey charts to visualize financial flows, such as inflows and outflows of capital in a business, giving a comprehensive overview of a company’s financial health.
5. Education and Research
Due to their clarity, Sankey charts are excellent tools for illustrating complex processes in educational settings. They are a staple in many scientific and engineering textbooks.
6. Information Visualization
The Sankey diagram is also becoming a favorite among data scientists for presenting datasets where the movement of information or activity matters most.
Conclusion
Sankey diagrams, or “Sankey Sauce,” add a visual flavor to the otherwise dry world of data analysis. The art of crafting a Sankey chart can be a fun, rewarding activity that allows us to unveil the secrets hidden within complex systems. The next time you have a chance to visualize a process’s flow, why not experiment with this unique approach and see what new insights you can uncover with Sankey Sauce?
