Flow analytics is a powerful tool that enables us to visualize how resources, data, or processes move between different categories or nodes in a system. One of the most effective ways to represent these flows is with a Sankey chart, a type of flow diagram that allows us to easily see where resources are coming from, where they are going, and how much of each resource is being transferred. In this article, we will explore the creation and applications of Sankey charts, discover their unique attributes, and see how they can be used to unleash the power of flow analytics.

The power of Sankey charts: A visual representation of resource flows

Sankey charts are a type of flow diagram that uses arrows to represent the movement of resources between different nodes. Each arrow’s width corresponds to the volume of flow, and the colors represent specific categories of resources or processes. The unique structure of Sankey charts makes them highly effective for visualizing complex flow relationships and identifying key influencers and bottlenecks in resource systems.

By looking at a Sankey chart, we can quickly understand:

1. Source and destination nodes: Each starting or ending point in the chart indicates where the flow originates or terminates.
2. Resource volume: The width of the arrows reflects the amount of flow between nodes, making it easy to identify high and low volumes.
3. Resource categories: Different colors help distinguish between diverse flows, allowing us to categorize similar elements from distinct ones.
4. Key influencers: A high volume of flow from a single source to another cluster may indicate a significant influencer.

Creating a Sankey chart: A straightforward process

Creating a Sankey chart involves a series of steps that transform data into a visual representation, highlighting the flows between nodes. Here’s a simplified process to get you started:

1. Define the nodes: The first step is to identify and name the sources and destinations. These nodes represent data points in your system.
2. Collect data: Gather data on the volume of flow between each node. This data might be in the form of percentages, volumes, or units.
3. Choose a tool: Sankey charts can be created in various tools, including Excel, tableau, and specialized software like SankeyFlow. Each tool has its own set of features for designing and styling charts.
4. Map the data: Input the node names and flow data into your chosen tool. Position the nodes and connect them with arrows, ensuring the data reflects the correct volume and direction.
5. Customize the appearance: Adjust the visual elements such as colors, width, and layout to enhance clarity and readability.
6. Analyze the chart: Examine the chart to identify key flow patterns, influencers, and potential bottlenecks.

Sankey chart applications: From industry insights to data governance

The versatility of Sankey charts extends across multiple fields, making them useful in both professional and personal contexts. Here are some common applications:

1. Business: In business analytics, Sankey charts are used to map supply chain flows, marketing channel effectiveness, and the distribution of resources.
2. Industry: Engineers and designers can use Sankey charts to analyze the energy usage in processes and systems, helping them optimize efficiency and reduce waste.
3. Government: Public sector professionals use Sankey charts to visualize the flow of funds within their budget or the movement of resources between departments and agencies.
4. Data governance: Data engineers leverage Sankey charts to understand the flow of data from various sources to destination systems, aiding in data mapping, lineage representation, and overall data management.
5. Environmental studies: Environmentalists can apply Sankey charts to visualize the movement of pollutants, resources, or energy between ecosystems and human systems.
6. Social sciences: Researchers in sociology, economics, or political science use Sankey charts to analyze the flow of information, trade, or influence between different groups or countries.

Unleashing the power of flow analytics with Sankey charts

Sankey charts are an effective tool for visualizing complex flow relationships, providing insights that help decision-makers understand and optimize resource allocation, process efficiency, and data usage. By transforming raw data into clear, visual representations, Sankey charts enable organizations to identify key influencers, streamline processes, and make data-driven decisions. Whether you are a business analyst, environmentalist, or data manager, harnessing the power of Sankey charts can offer a deeper understanding of your data’s journey and unlock valuable insights for improved performance.
