Introduction:
Sankey charts are a type of diagram that is used to visualize the flow of data, such as information, resources, or energy. They are particularly useful when you have a large amount of data to describe in a compact and easy-to-understand way. In this article, we will explore the basics of creating and interpreting Sankey charts, and then present some examples of their application in interactive maps.
What is a Sankey Chart?
A Sankey chart is a type of diagram that is typically used to visualize the flow of information or resources. They are rectangular in shape and are often used in conjunction with flow diagrams, which are used to show how different variables are related to each other. The flow of the lines in the Sankey chart can be shown to represent the flow of resources or the flow of information, and the labels on the arrows can provide details about the flow of data.
How to Create a Sankey Chart
To create a Sankey chart, you will need the following tools: a computer with a graphing calculator or a software program like Microsoft Excel, a digital image editor like GIMP, and ink or markers to draw the grid lines. You will also need access to a data source that you want to map onto the Sankey chart. Once you have all of these tools and a data source, you can start creating the chart.
To create a Sankey chart, you will first draw the grid lines on the graph. You can use a ruler or other measuring tool to create the lines, and then you can use ink or markers to draw the grid lines on the Sankey chart. You will then plot the data points on the chart, and you can label the nodes and arrows to indicate the source, destination, and flow of information or resources. Make sure to use enough lines for the data to be clearly visible, but don’t use too many lines because it can make the chart difficult to read.
How to Interpret a Sankey Chart
Once you have created a Sankey chart, you can interpret it to understand the flow of data or information. The data nodes on the chart represent the different variables that you want to map, and the lines between the nodes represent the flow of information or resources between those variables. The angle of the lines can give you a sense of how the flow is directed and the weight of the lines can give you an indication of the strength of the flow.
You can also use the arrows to indicate the direction of the flow. The up arrow means that the flow is moving up (towards the node) and the down arrow means that the flow is moving down (towards the node). The arrow can also indicate the direction of the flow and the color of the arrow can indicate the magnitude of the flow.
Examples of Sankey Chart Applications
There are many different ways you can use Sankey charts to map data, and they can be applied in a variety of fields. One example is in economics, where Sankey charts can be used to map the flow of investments and loans in the finance sector. Another example is in environmental science, where Sankey charts can be used to map the flow of water and chemicals between different sources and destinations. Sankey charts can also be used in public policy, where they can be used to map the flow of resources between different sectors of the economy.
Conclusion:
Sankey charts are a useful tool for mapping data, particularly when you have a lot of data to describe in a compact and easy-to-understand way. By creating a Sankey chart, you can understand the flow of information or resources and use it to make informed decisions. In conclusion, we hope that you have gained a better understanding of Sankey charts and their applications, and we encourage you to explore them further in your research or coursework.
