Sankey charts are a type of data visualization that can be used to represent complex flows and distributions. They are named after the Scottish engineer and inventor Thomas Sankey, who first used them in the 19th century to visualize steam engine processes. Since then, Sankey charts have become a popular and powerful tool for data analysts and researchers to visualize a wide range of flows, from energy consumption and production to information and financial transactions.
Creating a Sankey chart involves several steps. First, you need to gather and organize your data into a flow matrix or a set of linked data points. The data should include the source (or input), the target (or output), and the quantity or strength of the flow. The matrix or data set should also specify the dimensions that will be used to color and label the nodes and edges of the chart.
Next, you need to choose a tool for creating your Sankey chart. There are many options available, including software programs, online platforms, and even libraries for programming languages like Python and R. Some popular tools for creating Sankey charts include Tableau, Microsoft PowerBI, and Gephi. These tools typically provide a range of customizable options for adjusting the visual appearance of your chart, such as colors, labels, and layout.
Once you have your data and tool prepared, you can begin creating your Sankey chart. The process may involve adjusting the flow matrix or data set, manipulating the visualization settings, and adding labels and annotations. The goal is to create a chart that accurately represents the flow and distribution of your data while also being visually appealing and easy to understand.
So, what are the applications of Sankey charts? They can be used to represent a wide range of flows and distributions, such as energy consumption and production in industries, material and capital flows in supply chains, information and knowledge flows in organizations, and financial transactions in financial systems. They can also be used to visualize social and biological networks, as well as political and economic systems.
One of the strengths of Sankey charts is their ability to highlight the most significant flows and patterns in the data. By using colors, arrows, and labels, they can help identify the major contributors, the most efficient or inefficient components, and the overall direction of the flow. This can provide valuable insights for decision-makers, policymakers, and analysts who want to understand and optimize complex systems.
Moreover, Sankey charts can be used in a variety of formats and contexts. They can be created as static images or animated videos for presentations, reports, and educational materials. They can also be embedded in web pages or dashboards for real-time monitoring and analysis. They can be used in combination with other types of visualizations, such as bar charts, pie charts, or heat maps, to provide a more comprehensive and integrated view of the data.
In conclusion, Sankey charts are a powerful and versatile tool for data visualization that can help you unleash the power of flow in your work. They can help you uncover hidden patterns, highlight important flows, and communicate your findings effectively to your audience. Whether you are a data analyst, a researcher, or a designer, learning how to create and use Sankey charts can be a valuable addition to your skills and toolkit.
