Sankey charts are a powerful visualization technique for displaying complex relationships in data. They are particularly useful for showing the flow between different entities in a system, such as people, money, or objects.
In Sankey charts, nodes represent the entities being flowed between, while lines connect these nodes and represent the direction of flow. The lengths of the lines can be used to indicate the amount of flow. Using Sankey charts, you can easily understand the overall flow within a system, as well as how different entities are related to each other.
Sankey charts can be used in a variety of settings, from finance and economics to social sciences and biology. For example, in finance, Sankey charts can be used to explain the flow of capital into and out of different sectors of the economy. In the social sciences, they can be used to explore the ways in which different groups within a society interact with each other. And in biology, they can be used to show the paths that molecular signals take to traverse cells and tissues.
One of the strengths of Sankey charts is that they are relatively easy to create and understand, even for those with limited knowledge of data visualization. You simply need to arrange the nodes on a horizontal axis and the lines on a vertical axis, and connect the nodes as you see fit. The result is a visual representation of the flow, which can provide valuable insights into the dynamics of the system.
There are a number of online resources for learning Sankey chart creation and application. For example, the Stanford Visualizing Data course provides a guide to how to create Sankey charts using the “NodeLink” and “Gadget” software. Additionally, you can learn about Sankey charts in books on data visualization and organizational communication.
In conclusion, Sankey charts are a valuable tool for understanding complex relationships in your data. They are easy to create and understand, and can provide valuable insights into how different entities interact and how systems function. Whether you’re working in finance, social sciences, biology, or any other field, Sankey charts can help you see the bigger picture and make more informed decisions.
