2. Creating Sankey Diagram using Tableau
When you have more complex data and want to use a visualization tool other than Excel, Tableau is a suitable solution.
At the organization level, dealing with large volumes of data requires a visualization tool. Tableau makes it easy to visualize data flow in a Sankey diagram. Unlike Excel, Tableau is an online data visualization tool.
To use it, follow the steps below:

Step 5: Next, customize the data and features as you want them to appear on the Sankey diagram. These include the data values, name, graph type, color, size, and path.
A drawback to using Tableau is that you should have design skills. You will need to create custom SQL when creating a visual format for your data.
Tableau is an excellent visualization tool for professional data analysts. If you do not have data representation skills, it can be challenging to use the software.
