Sankey charts were developed by the Dutch mathematician, Benoît Mandelbrot, in 1966 and are widely used for visualizing data efficiency. They are a type of flow diagram that represents a network of inputs and outputs where each node represents a specific entity and each flow represents a flow of resources or actions from one entity to another. In this article, we will explore the secrets of Sankey charts and how they can be used to unlock the power of visualizing data efficiency.
What are Sankey charts?
Sankey charts are a type of flow diagram that are used to visualize data efficiency. These charts are designed to represent the flow of resources or actions from one entity to another and are often used in fields such as economics, engineering, and social sciences.
The basic structure of a Sankey chart consists of a network of nodes (entities) and flows (resources or actions). Each node represents a specific entity, and each flow represents a flow of resources or actions from one entity to another. Sankey charts can be used to compare the efficiency of different sources or entities by using different colors for the sources and different arrows to describe the direction of the flows.
How do Sankey charts unlock the power of visualizing data efficiency?
Sankey charts can be used to unlock the power of visualizing data efficiency in a variety of ways. Here are some of the ways in which they can be used:

1. Visibility of data sources and goals
   Sankey charts can be used to visualize the sources and goals of a set of activities or data. This makes it easier to identify the key areas of focus and helps to determine the effectiveness of different sources or activities.

2. Analysis of the network of flows
   Sankey charts allow for the analysis of the network of flows, which can help to identify bottlenecks or areas for improvement. By visualizing the flow of resources or actions across different entities, it is possible to identify areas where there are inefficiencies or where specific resources are being wasted.

3. Facilitation of decision-making
   Sankey charts provide a visual representation of the flow of data, which can be used to facilitate decision making. It allows decision makers to identify the best sources of data or actions and understand the implications of different choices.

   There are a variety of ways in which Sankey charts can be created and used, ranging from simple bar charts to more complex networks. In this article, we will show you how to create a simple Sankey chart using Microsoft Excel and how to use it to unlock the power of visualizing data efficiency.
   Creating a Sankey chart in Excel
   To create a Sankey chart in Microsoft Excel, follow these steps:

   1. Open a new Excel workbook and create a new worksheet.
   2. In the first column, create a column for the sources and in the second column, create a column for the nodes.
   3. In the sources column, list the names of the entities or the sources of data.
   4. In the nodes column, list the entities or actions.
   5. In the flow column, create a column for each flow, listing the type of flow (such as input, output, or direction) and the nodes that the flow represents.
   6. Double-click on the node that represents the data source or goal to highlight it.
   7. In the arrow area, write the source name, followed by the flow name and the target node name.
   8. To add additional nodes, select the nodes that you want to remove from the chart, open the “View” tab, and select “Group”. This will create a new group of nodes with the same source, but may prevent the chart from being properly displayed.

Using Sankey charts in Excel
Once you have created your Sankey chart in Excel, you can use it to unlock the power of visualizing data efficiency. Here is an example of how to use a Sankey chart in Excel to compare the profits of different sources or entities:
1. In the first column of your chart, enter the names of the sources or entities.
2. In the second column of your chart, enter the names of the profits or outcomes.
3. In the third column of your chart, enter the amounts of each source or entity, followed by the profit or outcome for each source or entity.
4. In the flow column of your chart, use the arrows to represent the flow of profits or outcomes.
5. This will display a Sankey chart that visualizes the network of flows representing the sources and outcomes of the data. By comparing the profits or outcomes of different sources or entities, it is easy to identify areas for improvement.
6. To use the chart, you can click on a source or entity to see a more detailed comparison of the profits or outcomes of that source or entity.

In conclusion, Sankey charts are a powerful tool for unlocking the power of visualizing data efficiency. By creating a Sankey chart in Microsoft Excel and using it to compare the sources and goals of a set of activities or data, decision makers can identify areas for improvement and drive more efficient and effective processes.
