Sankey charts are a type of data visualization that have gained popularity in recent years due to their ability to help visualize complex flows and connections in a way that is intuitive and easy to understand. In this article, we will explore the concept of Sankey charts and how they can be used to unravel complex data and uncover valuable insights.
What is a Sankey Chart?
A Sankey chart is a type of flow diagram that represents data flows or material flows as a network of nodes and links. The width of each link is proportional to the flow volume it represents, making it easy to identify the most significant flows in the data. The chart is typically used to show the distribution of a certain resource or flow between different nodes in a process, making it ideal for displaying complex data over time and for different groups or individuals.
Creating a Sankey Chart
To create a Sankey chart, you will need to gather the data that you want to visualize. This data should include the source and destination of the flow, as well as the volume or value of the flow. You can then input this data into a Sankey chart library or software, such as D3.js, Bokeh, or Plotly, which will generate the chart based on your data.
Once your chart is created, you can customize it to make it more visually appealing and easier to understand. For example, you can add labels and tooltips to your nodes and links, adjust the color scheme, add annotations, and modify the shape of the chart. You can also add animations to help users understand the flow of data more intuitively and give them a sense of the data’s movement over time.
Applications of Sankey Charts
Sankey charts have a wide range of applications, including:
- Business: Sankey charts can be used to visualize sales flows between different branches or departments, employee retention rates, customer journey analysis, supply chain management, and more.
- Energy: Sankey charts can be used to analyze energy flows in a network, such as electricity grids, gas pipelines, or hydroelectric power stations.
- Environment: Sankey charts can be used to analyze the flow of energy, CO2 emissions, water usage, and other environmental impacts in a system.
- Public health: Sankey charts can be used to analyze the flow of patients through a healthcare system, the progression of a disease or epidemic, and the allocation of resources such as vaccines or treatments.
Unraveling complexity with Sankey charts
Sankey charts can help unravel complexity in data by providing a clear and intuitive way to visualize relationships between different variables. By identifying the most significant flows and connections in the data, users can uncover valuable insights and make data-driven decisions. Furthermore, Sankey charts can be used in conjunction with other data visualization techniques, such as heat maps and graphs, to provide a more comprehensive view of the data.
In conclusion, Sankey charts are a valuable tool for visualizing complex flows and connections in data. By understanding the concept behind these charts and how to create them, you can use them to uncover valuable insights and make data-driven decisions in a wide range of applications.
