Sankey charts, also known as process flow diagrams or multi-dimensional bars, are a versatile and effective tool for visualizing and analyzing network data. They are widely used in fields such as business, engineering, and social sciences to visually represent and understand complex relationships and chains of action. In this article, we will explore the secrets behind creating and understanding sankey charts, as well as explain their applications in different contexts.
How to Create Sankey Charts
Creating a sankey chart is a relatively simple process, but it requires a clear understanding of the data and the relationships that need to be represented. Here are the basic steps to creating a sankey chart:
1. Gather Your Data: First, gather all the data you need to create your sankey chart. This includes information about the nodes or elements that will represent the various entities in your network, as well as the relationships and connections between them.
2. Select a Node and Arrow Size: Once you have your data, select the nodes and arrows you want to use in your sankey chart. For each node, select a size for the node itself (usually a label or icon) and pick the color and shape of each arrow.
3. Plot the Nodes and Arrows: Place the nodes and arrows on the diagram, using the locations and relationships in your data. Avoid any errors in layout and make sure everything is straight and legible.
4. Connect the Nodes and Arrows: Use arrows to connect the nodes and arrows, creating a flow of information through the chart. Make sure the arrows are clearly labeled and that each arc has a flow that starts with each node.
5. Customize the Layout: Finally, customize the layout of your sankey chart to make it more visually appealing and easier to read. This can include adjusting the color scheme, adding gradients, or changing the scale of data.
Sankey Charts in Different Contexts
Sankey charts have many applications in various fields, including:
- Business and Finance: These charts can be used to visualize supply chain processes, business processes, and the various resources and components that make up a company.
- Engineering and Design: These charts can be used to illustrate the flow of information and processes in different engineering fields, such as energy, manufacturing, and construction.
- Social Sciences: Sankey charts can be used to visualize the flow of social and political relationships, as well as the interplay of different actors and institutions. They can also be used in public health, environmental science, and other fields to visualize the transmission of diseases or pollution.
In conclusion, sankey charts are a powerful and versatile tool for visualizing and understanding complex network data. With a clear understanding of data and relationships, and some basic layout and color customization, you can create beautiful and informative sankey charts to represent and interpret various kinds of network data.
