The Sankey chart is a popular data visualization tool used to simplify complex information by breaking it into flow diagrams. In this article, we will explore how Sankey charts work, how to create one, and the various applications they can help you to explore.
The Sankey chart is a type of diagram that shows the flow of information or data. It uses a directed graph, which consists of nodes (source nodes) and directed edges that connect them to other nodes. The flow direction of the edges represents the direction of the information or data flow.
Sankey charts are often used in situations where there is a need to compare different sources of information or data. For example, imagine two different systems for collecting water from a shared source, one that uses multiple buckets to collect water and one that uses one large bucket. By creating a Sankey chart that shows the flow of water into and out of these two systems, a user can easily compare the efficiency of each system and optimize resource usage.
To create an intuitive layout for a Sankey chart, it is important to follow several key rules:
1. Choose a consistent color scheme for nodes and edges. This will make the chart easier to read and understand.
2. Choose a scale for the size of the nodes and edges that makes the chart visually appealing. This will help to avoid cluttered and hard-to-read charts.
3. Choose a clear legend with the label and scale for both source and destination nodes. This will make it easy for readers to understand the meaning of the graph.
There are several tools available for creating Sankey charts, and the best one will depend on your specific needs. Some popular options include Tidy Sankey Charts, Graphviz, or the official Sankey Chart Tool from D3.js. These tools can help you generate interactive and customizable Sankey charts quickly and effectively.
In conclusion, Sankey charts are a valuable tool for simplifying complex information and visualizing the flow of data. By creating intuitive layouts and following a few simple rules for node and edge placement, you can easily explore and analyze large and multi-dimensional datasets. With the availability of various software tools, creating and presenting Sankey charts has never been easier, and you can now use this powerful tool to help you in different fields, from business analytics to environmental sciences.
