Sankey charts are a visual representation of network relationships, which are essential to understanding how one system is connected, related, or dependent upon another. As a visual tool, they are particularly useful for exploring connections and relationships between various systems or processes.
Sankey charts can be created in a variety of formats and are commonly used in economics, engineering, and social sciences. They can be used to visualize the flow of information or financial transactions, or to map out the relationships between different systems in a complex ecosystem. Sankey charts can also be modified to visually represent other types of relationships, such as the flow of energy, or the movement of different organisms within a community.
In this article, we’ll explore the creation and applications of Sankey charts. We’ll also discuss the visual complexity of Sankey charts and how they can be a powerful tool for exploring connections and relationships.
Creating a Sankey Chart
A Sankey chart is made up of multiple line segments connected end to end to create a series of paths between different systems or processes. Each segment of the line represents a process or system, and the direction of the path specifies the direction of flow. For example, if a Sankey chart represents information flow between two entities, the line segments from the sender to the receiver might all point in a particular direction to indicate that information goes one way from sender to receiver. Conversely, lines for information flow from the receiver to the sender would all point in the opposite direction.
Sankey charts can be created in a variety of formats, including as PDFs, images, or even as text content with a tool for creating illustrations or diagrams. Each format comes with its own set of tools for creating and editing data, and can be more or less complex depending on the level of detail and complexity desired.
Sankey charts can represent a wide range of information, and may be used to visualize a range of relationships between different systems or processes. For example, a medical study examining the flow of information between researchers, doctors, and patients might use Sankey charts to represent the flow of information from the researchers to the doctors and then on to the patients. In this case, the flow of information would be represented by lines from the researchers to the doctors, then from the doctors to the patients in a complex, branching network.
The visual complexity of Sankey charts can be a powerful tool for exploring relationships and connections. When multiple lines are connected, it’s easy to see how different processes or systems are connected, and how they may interact with one another. Sankey charts are particularly useful for exploring relationships between systems that are relatively disconnected, or where the flow of information between them is highly complex or dynamic.
Sankey charts can also visually represent other types of relationships, such as the flow of energy or the movement of organisms within a community.
When creating a Sankey chart, there are a number of tools available for selecting and formatting data. For instance, many open-source tools such as R or Python also provide libraries that can interface with data sources. Also, the software allows creating, editing and importing data in various formats including Excel, CSV, JSON, SQL etc. This is a good option if you have extensive data. However, if the data is simple, then you can use basic drawing tools such as Microsoft Excel.
In summary, Sankey charts are a powerful tool for visualizing connections and other network relationships. By creating and modifying lines in a variety of line segments, you can see how different systems or processes are interconnected. With the complexity of Sankey charts and the numerous tools available for creating and editing data, they can serve as an effective tool for exploring complex relationships and interactions between systems. However, it is important to use this tool with care. For example, the flow of information between different systems may be unpredictable, which can lead to a less accurate assessment. Additionally, a Sankey chart can only represent a small set of relationships between different system or processes, and may not show all possible relationships that exist. It’s important to use the tool with an understanding of what it signifies in the relationship between different nodes and edges in the chart.
