Introduction
Sankey charts are a powerful tool used to visualize the flow of data from one entity to another. They use simple lines to illustrate the flow of different elements, such as materials, people, money, or information. Sankey charts are widely used in fields such as economics, engineering, and sociology, where large amounts of data must be analyzed and represented visually.
The Visual Guide to Analyzing Complex Data Flow
The key to unlocking the power of Sankey charts is to choose the right data to represent and analyze carefully. Sankey charts can represent complex data flows that are difficult to visualize otherwise. For example, the flow of money from a government budget to the private sector can be visualized with a Sankey chart, while the flow of ideas between two departments can be visualized with a Sankey chart of an entire project.
Here are some steps to creating a Sankey chart that can effectively visualize data flow:
-
Choose the right axes: When creating a Sankey chart, it is essential to choose the right number of axes. Too many axes can make the chart overwhelming and difficult to interpret, while too few can limit the representation of data. A good rule of thumb is to have one or two axes for clarity.
-
Determine the scale: The scale on your Sankey chart should reflect the magnitude of the flow you are analyzing. The closer the flow to the axes, the larger the value of the flow represented. This is to ensure that the data being represented is easily interpretable.
-
Decide on the line type: Choose the appropriate line type, such as a diamond or a single arrow, for each component in your Sankey chart. A diamond represents a connection between two components, while an arrow represents the flow of data.
-
Determine the color: Choose the appropriate color for each component in your Sankey chart. Depending on the nature of the flow represented, colors can reflect different values, emotions, or situations. For example, a positive flow might be represented in green, while a negative flow might be represented in red.
-
Decide on the orientation: Decide whether your Sankey chart will be horizontal or vertical. Whether to use horizontal or vertical formatting largely depends on the direction of the flow you are analyzing.
Application
Sankey charts can be applied in various fields such as finance, supply chain, social sciences, and engineering. In finance, Sankey charts can be used to track the flow of money through different components of the economy. In supply chain, Sankey charts can be used to represent the flow of materials from the original supplier to the final consumer. In social sciences, Sankey charts can be used to represent the flow of emotions between different people in a group.
Conclusion
Sankey charts are a versatile tool for analyzing complex data flows. They allow you to visualize the flow of data from one entity to another in a simple and effective manner. By following the steps outlined above and analyzing the nuances of your data flow, Sankey charts can reveal insights that traditional data analysis techniques alone cannot.
