Visualizing Complex Flows with Sankey Charts: A Whimsical journey to Efficiency
In the digital age where data is king, the art of visualizing complex information has grown more crucial than ever. One fascinating tool that has emerged from the need for creative data representation is the Sankey chart. Often thought of as a diagramming technique that belongs strictly in the domain of business and logistics, Sankey charts serve a purpose far beyond the mere presentation of supply chains and resource allocation graphs. They’re artistic, they’re educational, and at their heart, they’re about efficiency.
Sankey charts—also known as Sankey diagrams—are a type of flow diagram that illustrates relationships between different metrics that contribute to a total. Named after their eponymous creator, mathematician Arthur B. Sankey, they’re easily recognized by their boxed, bar-like structures connected in a series of flow lines depicting proportions and ratios of the data being visualized.
The genesis of the Sankey chart began in 1937, when Sankey created a diagram for the British Coal Utilization Research Association to visualize the percentage of coal converted to useful energy versus waste. Today, the applications are as diverse as the flows of data we seek to understand. From project management to financial analysis, from environmental studies to social media metrics, Sankey charts serve as a visual narrative tool, making the complex discernible even to the untrained eye.
Creating a Sankey chart is like embarking on a journey, stitching together different threads of data to form a cohesive story. It is a step-by-step process of sorting, categorizing, and connecting the information points. Beginners should first choose a dataset that they want to analyze, then design the structure of their flow. The idea is to start with the largest component of the flow, placing it at the beginning and breaking it down into smaller components, aligning them on the same level to signify equivalence.
The next phase involves drafting the chart, meticulously arranging the boxes and lines so that they accurately reflect the relationships and rates between the various data points. While this is a time-consuming process, it is a rich ground for creativity. The whimsical nature of a Sankey chart comes from the possibilities of color, shape, and movement that one can introduce. The boxes can be designed to look like anything, from clouds and mountains to futuristic tech and whimsical animals. The lines connecting them morph into rivers, roads, and winds, with each unique visual element telling its own story, keeping the viewer engaged and curious.
Once the chart is complete, it serves not just as a piece of art, but as a form of communication that cuts through the noise of raw numbers, data points, and metrics with a clarity that’s difficult to achieve with other visual formats like bar graphs or pie charts. The simplicity of a Sankey chart is deceptive: it contains the complexity of its data within a system that’s easy to understand and navigate.
The journey ends, yet the lessons continue. From the smallest box to the longest line, every element in a Sankey chart has a place and serves a purpose. So, the next time you’re faced with a sea of data that seems like a mountain to visualize, remember: you’re embarking on a journey unlike any other—a journey of efficiency, art, and storytelling, guided by the meticulous design and colorful aesthetics of the charming Sankey charts. Your creative maps await.
