In the ever-surging stream of data, conveying complex information with lucidity has emerged as an essential skill for both data designers and analysts alike. A cornerstone of this effort to make data more comprehensible is the use of visual harmony techniques, which turn chaotic data into coherent and meaningful visual stories. Amongst a panoply of tools built for such tasks, one stands out – the Sankey chart. Born from a family of diagrammatic data visualization, Sankey charts offer an intuitive and powerful means for understanding the flow between various entities, providing an overall picture of a system and highlighting the relationship within it.
Sankey charts derive their elegance and functionality from their simple, yet effective design. This visual harmony in data portrayal comes predominantly from the division of different segments between the flows, usually signified by various colors. The width of these segments clearly represents the total amount of flow, so at a quick glance, one can get a good sense of the volumes involved. At the heart of a Sankey chart, are arrows that illustrate various flow paths. The longer the flow path, the more significant the interaction or transformation within that path, giving users insights into the process or system at hand.
Now, let us delve into how to create a Sankey chart and its various applications:
Creating Your Sankey Chart:
1. Understanding the Data: The first step is to understand your data and its flow. Categorize your data into source / input, transformation, and output flows, and quantify the value or volume associated with each flow. The more granular you are in detailing the data, the more insightful your analysis will be.
-
Tool Selection: There are numerous tools available nowadays to create Sankey charts, ranging from easy-to-use online platforms like Sankey diagrams or simply color to professional software like Tableau or Microsoft Excel with their built-in Sankey chart functions.
-
Chart Construction: Start by adding your nodes, which are typically the sources / inputs and outputs of your flows. Draw your links to represent the flows and ensure they connect nodes meaningfully. Each link should be proportional to the value or volume it represents.
-
Customization: After the initial drawing, customize your chart with colors, labels, and annotations if needed to refine and highlight key points.
Applications of Sankey Charts:
– Resource Allocation: You can use Sankey charts to analyze the allocation of resources in a project or business, demonstrating how funds, workforce, or materials are divided up and used.
-
Energy Consumption: These charts are frequently used to represent the flow of energy, illustrating how energy is sourced, used, and consumed within a system.
-
Internet Traffic: Network engineers use Sankey charts to visualize web traffic patterns, helping them to identify potential bottlenecks or inefficiencies in their systems.
-
Finance and Banking: In these sectors, Sankey charts are often utilized to illustrate the flow of loan or investment monies, enabling banks or financial institutions to understand better how funds are allocated and distributed.
-
Waste Reduction: By visualizing the process of waste management and reduction in an organization, Sankey charts help identify wasteful areas and suggest ways for improvement.
In summary, the application of Sankey charts transforms the daunting world of complex data into a series of easily interpretable and beautiful visual representations. By judiciously segmenting and coloring the data, one can derive substantial insights from the patterns within the flows. As data continues to grow, these charts will undoubtedly be one of the most revered tools for the visual manipulation of flows and processes.
