A Sankey chart is a type of network visualization that is particularly well-suited for presenting complex data. In recent years, Sankey charts have gained popularity in the fields of economics, healthcare, and ecology as a means of presenting data in a more intuitive and compelling way. In this article, we’ll take a look at how to create a Sankey chart, as well as some applications of Sankey charts in various fields.
The Create Sankey Chart: A Step-By-Step Guide
To create a Sankey chart, you’ll typically start by collecting data for your network. In Sankey charts, nodes are typically used to represent the sources or sinks of the data, while the links represent the flow between these nodes. The order in which you place the nodes and links is important, as the flow of information or resources can be more easily demonstrated by ordering them from highest to lowest. Once you have your data collected, you can start to create your Sankey chart.
Here is a step-by-step guide to creating a Sankey chart:
1. Collect Your Network Data: Collect your network data, which will be used to create your Sankey chart.
2. Select the Type of Chart: Decide on the type of Sankey chart you want to create. There are several types of Sankey charts, including ordered and unidirectional Sankey charts, which are more commonly used in industries such as healthcare and environmental policy.
3. Design the Chart Layout: Design the layout of your Sankey chart. In order to create an effective Sankey chart, you’ll need to pay attention to the order in which your nodes and links are arranged.
4. Add Connections: Add connections to your Sankey chart by choosing the type of connection you want to make, such as a straight line or curved line.
5. Add Descriptions: Add descriptions to your Sankey chart. These can be either text or numbers that represent the flow of data, resources or messages.
6. Analyze Your Data: Analyze your network data to determine the optimal connections for your Sankey chart.
Applications of Sankey Charts
Sankey charts are a versatile tool that can be used in a wide range of fields. In the world of economics, Sankey charts can help illustrate the movement of capital, resources, and information throughout a network. In industries such as healthcare and environmental policy, Sankey charts can be used to identify and prioritize initiatives that can help improve the flow of critical information.
For example, in healthcare, Sankey charts can be used to illustrate the flow of resources across hospitals and clinics to determine the optimal way to distribute resources to meet patient needs. In the environmental policy field, Sankey charts can be used to identify the flow of waste and pollution across industrial sites to determine the most effective way to reduce these issues.
In conclusion, Sankey charts are a powerful tool for presenting complex networks in a more intuitive and compelling way. They are a versatile tool that can be used in a wide range of fields, including economics, healthcare, and environmental policy. If you are interested in using Sankey charts to demonstrate your data, you should consult with a professional to ensure that you are presenting your data effectively.
