Sankey charts are a powerful tool for visualizing complex data. In this article, we will explore the various ways to create a sankey chart and its applications.
How The Sankey Chart Works
A sankey chart is a type of network visualization tool that uses a series of bars to visualize the flow of data. The bars connect the start and end nodes, and the labels above them indicate the flow of data between the two nodes. The sankey chart has two main types:
-
Single sankey chart – This type of sankey chart visualizes the flow of a single node. It involves placing two nodes on the horizontal axis and connecting the start and end nodes in an upward arrow shape. The flow of data between the two nodes is represented by a series of horizontal bars.
-
Multi-node sankey chart – This type of sankey chart visualizes the flow of multiple nodes. It involves placing multiple nodes on the horizontal axis and connecting them through an arrow-shaped line. The flow of data between the nodes is represented by a series of vertical bars, which can either ascend or descend according to the direction of the flow.
What To Know Before Creating a Sankey Chart
To create a sankey chart, you must first select the nodes you want to visualize. These are typically the data points in your dataset. Next, you need to determine the direction of flow, which is typically represented by the color of the bars. The flow direction can be vertical or horizontal.
You should also add labels to the nodes and arrows to represent the direction of flow. Finally, you should choose a color scheme that is legible and makes it easy to read the chart.
Sankey Chart Applications
Sankey charts are primarily used to visualize complex data, such as network traffic, supply chain flow, and resource usage. They can be used to compare data between different locations, to analyze social networks, or to understand the flow of goods and services.
One of the benefits of sankey charts is that they are easy to understand and can easily convey information. They are also visually appealing and can help make complex data more accessible to non-technical users.
Overall, sankey charts are a valuable tool for visualizing complex data and can unlock insights that were previously inaccessible. They can be used to understand social networks, supply chains, and other complex data, making them a valuable addition to any visual analytics toolkit.
