Sankey charts have become increasingly popular in the field of data analysis and visualization. They are particularly useful for analyzing complex networks, such as those found in social media, online search, web technology, scientific research, and more. In this article, we will discuss the creation and applications of Sankey charts and how to use them to unlock data.
Sankey chart definition
A Sankey chart is a type of network diagram that displays the flow of information or resources between different nodes or nodes. It is a widely used tool for analyzing complex networks, such as those found in social media, online search, web technology, scientific research, and more. A sankey chart consists of a node for each element of the network, a line for each flow of data between nodes, and arrows pointing from one line to another to indicate that there is a flow of data in one direction.
How to create a Sankey chart
Creating a Sankey chart is relatively straightforward, but you will need to have a solid understanding of networks, information flow, and arrows. Here is a step-by-step guide on how to create a Sankey chart:
1. Identify the network you want to analyze. This will be the base of your chart where all the nodes and flows are added.
2. Define the nodes of the network. Each node represents an element, such as a user, a product, or a service that is part of the network.
3. Create the flows by determining which nodes are being connected by a line. The line can be directed or unidirectional, depending on the flow of information or resources between the nodes.
4. Define the arrows by indicating the direction of the flow of information or resources. The arrows can point to the left or right of the chart depending on the flow direction.
5. Add the labels to inform the reader about the nodes, flows, and arrows. These labels can be placed on the edges of the chart, below the headings, or in text annotations.
Examples of Sankey charts
Sankey charts can be used to analyze various types of networks. Here are some examples of how to use Sankey charts:
1. Social Networks: Sankey charts can be used to analyze social networks such as online social media, such as Twitter, Facebook, and Instagram. To visualize the flow of information or resources between different users, nodes can represent users, a line can represent Twitter shares, and arrows can represent how many people are following someone.
2. Search Networks: Sankey charts can be used to analyze search networks such as an online search engine. The nodes can represent different search queries, and the flows could represent the number of people who found a search query on a search engine.
3. Web Technology: Sankey charts can be used to analyze web technology networks where nodes represent different websites, and the flows represent links between websites. Arrows can indicate the direction of the links between the nodes.
4. Scientific Research: Sankey charts can be used to visualize the flow of information and resources in a scientific research network. The nodes can represent scientists, and the flows could represent the flow of ideas, research papers, or patents.
In conclusion, Sankey charts are a powerful tool for analyzing complex networks. They can be used to visualize the flow of information or resources between different nodes or nodes. It is essential to have a good understanding of networks and information flow to create a Sankey chart that accurately represents the network being analyzed.
