How to Create a Sankey Diagram in Google Sheets?

Data is a double-edged sword. On the one side, data is extremely valuable and allows you to learn issues in your existing processes to improve them. The not-so-nice side of data is that it is incredibly difficult and time-consuming to extract actionable info from it. In this how-to guide, you will learn How to create Sankey Diagram in Google Sheets to better understand how data helps you make insight-driven decisions regarding your business strategy.

What is a Sankey Chart?

When you’re ready to visualize your data, you have a lot of different chart options available. Often, you need to think about the data that you want to model, its purpose, and how to best display the information visually.

One option is a Sankey chart.

Definition: A Sankey diagram depicts a flow from one set of values to another. The two items being connected are referred to as “nodes.” The connections are labeled as “links.”

Components of Sankey Diagram:

To reiterate, there are two main components to a Sankey chart:

1. Nodes: The vertical bars in these examples are the nodes. The size of the node reflects its value, similar to a bar graph.
2. Links: The horizontal flow lines that connect nodes are the links. The color of the link matches the node. The wider the link, the higher its value.

There are multiple data structures that can be expressed with a Sankey diagram. Two of the most common are:

1. Evolution: The nodes reflect 2 or more periods or stages. The links between the stages allow you to see how the nodes have evolved over the different states.
2. Source to end: Total amounts are reflected on the left side of the chart as nodes. The flow of the links show where that amount goes and ultimately ends up. Some source-to-end Sankeys will also have an intermediate step in the middle of the chart.

How to Draw a Sankey Diagram in Google Sheets?

We assume that we’ve got our data finalized in Google Sheets, the next step is to turn the raw and difficult-to-work-with spreadsheet into an engaging and helpful Sankey diagram.

Step 6: Once you’ve arranged the data into the right options in the ChartExpo interface, press “Create Chart” at the bottom of the menu.

The resulting chart should look something like this:

Step 7: You may notice that the chart looks a little dull and is lacking certain elements, like a title, level headings, colors and more. Click on the “Edit chart” icon in the top menu, as shown in the following image:

Step 8: To add a title to the chart, click on the edit pencil next to “Chart Header” at the top of the diagram.

You can change the name of each level as:

Step 8: After clicking the “Edit Chart” icon, you’ll enter editing mode. You’ll notice pencil icons next to each chart component. Clicking on these will allow you to edit each individual node color, header, etc.

For example, the following screenshot shows you the editing properties for the first level of nodes.

Step 10: When you’re finished editing your Sankey diagram in Google Sheets, exit the editing mode. Now, you have a polished Sankey chart that is ready to be included in your reports.

When Should You Use a Sankey Chart?

Every chart has its own advantages and purpose. As mentioned, you need to think about what chart to use for each set of data. Let’s further explore the times when it is best to use a Sankey diagram to chart your Google Sheets data.

• You can use the Sankey chart to visually express a complex process while focusing on a single metric, aspect, or resource. For instance, if your team is making a decision about ad spend or even how time is being managed in the group, a Sankey chart is a great way to show the breakdown of this information.
• One of the coolest features of the Sankey diagram is the multiple levels that you can view the same data from. You can get a high-level view, as well as a more zoomed-in view of the data in one chart. Interactive elements will allow people to drill down as deep into the data that they want or need.
• When you want to measure dominant contributors in your campaigns, the Sankey chart makes these top-performers stand out. This helps you identify areas with the largest opportunities.

Examples of Sankey Charts in Google Sheets

To give you an idea of how Sankey Visualization looks like, here are some examples of Sankey Diagram:

Example 1: Energy Flow Management

In the above example, we can see the energy flow in each phase from production source to end usage.

Example 2: Google Ads Campaign Demographic Analysis by Device

In the above example, we can see each device type broken down by gender and age demographics.

Example 3: Impression Share by Device Type and Match Type

This chart shows how the impression share is broken down by device type and match type in the same chart.

When Should You Avoid Using a Sankey Diagram?

Along with knowing when to use a Sankey diagram, you should also know when it is not applicable or helpful for charting your data.

• Sankey charts can first appear overwhelming, especially if you aren’t familiar with this type of visualization. Audiences may not be as comfortable with Sankey diagrams as they are with bar, line, pie or scatter plot charts.
• Since not everyone is used to seeing a Sankey chart, you may have to spend some time explaining what is being shown. This is particularly true if your Sankey chart involves many different nodes and levels.
• Sometimes, the links between nodes become so crossed that it is difficult to compare flows, especially when their values are very similar (the widths are the same).

Things to Consider Before Making a Sankey Diagram in Google Sheets

To be absolutely certain that a Sankey chart is the best option for your data, there are a few things that you should ask yourself:

• Are there any other options in the ChartExpo library of charts that better depict the information?
• Do you want the audience to perform a certain action, or are you just trying to tell the story behind your data?
• Does your audience have enough experience with charts to make sense of a complex Sankey diagram?
• Charts are designed to make a fact very evident. What fact does your Sankey chart best display to viewers? Is this what you intended?

Why it is Important to Chart Your Data?

The real problem is that your business processes produce a sea of data at all times. Staying afloat in these rough waters is not easy. If you aren’t careful, you can easily drown in it.

Oh, and did we mention that the data is constantly changing? Thus, you need to be swift in your ability to analyze the information. Otherwise, you’ll be drawing conclusions from data that is well past its shelf-life.

All of the pressures of managing and analyzing data leads to what is known as analysis paralysis. This is essentially a case where the data becomes so overwhelming that it is almost impossible to make any sort of decision.

To overcome the risk of data paralysis, you need to use charts and visualizations.

When you turn raw data into a visual format, you process the information much faster and the insights become easier to obtain.

It’s simple: charting your data is the most efficient way to understand the story behind the numbers. Your brain will seriously thank you because visuals are its preferred delivery method.

But, it’s not just about reducing headaches and preserving your mental health. Your brain also processes visual data 60,000 times faster than text or numbers.

Thus, taking raw data and presenting it in a visual model should be an essential step in your analysis process.

If you’re analyzing data in a spreadsheet, you’re wasting valuable time that could be spent on other tasks.

Charting data is particularly important for large or complex data sets. If you were to analyze it by hand, it could take you hours. However, once you chart the data, you can physically see what’s happening.

As soon as you see it, you get it.

Additionally, charts are universal. We’re all familiar with them and can interpret the insights being depicted. They are effective tools when you need to communicate results to others that are less familiar with your campaign data.

Here are some additional ways that charts can benefit your organization:

• Discover correlations and other relationships between campaign metrics and dimensions.
• Compare data from past and current periods to see trends over time.
• Know how frequently these trends and patterns occur so that you can prepare and react ahead of any changing conditions.
• Examine the market as a whole to see what opportunities and risks exist, how target audiences are behaving, what strategies competitors are using, and more.
• Understand what areas can be left alone and what areas need your direct attention. This is also known as risk and rewards analysis.
• React quicker to market changes and be the first to capitalize on the fresh opportunities.
