Sankey charts are a powerful and versatile tool that can be used to illustrate relationships and connections between different variables in data. This article explores the basics of Sankey charts, shows how to create one, and shares some ideas for using them to improve data visualizations.
Sankey charts are a type of diagram that uses a flow diagram format, with each individual represented by a link of solid or hollow line. The key is to determine which variables are represented in each node (or circle) and to connect them with links that show the flow of data between them.
Creating a Sankey chart is easy once you know the basics. First, choose the variables you want to represent, and decide on which variables to use in each node and which variables to connect to each other. You can create one of these charts using software like Tableau or Microsoft Power BI, which can then be shared with others to view in real-time. Alternatively, you can also use Excel’s in-built pivot tables to create a Sankey chart.
With these charts, you can easily visualize complex data relationships and connections. For example, you can use a Sankey chart to show the flow of traffic between different cities in a region, or to track the flow of money between different departments within a business. You can even use these charts to show how different factors influence each other, such as how the price of a car affects its fuel efficiency.
Another benefit of Sankey charts is that they can also be used to highlight the importance and contribution of certain variables. You can use different colors and line widths to separate different variables, which makes it easy to highlight the most important ones and understand their impact on the data under investigation. This information can be particularly useful for stakeholders or decision-makers who want to better understand and prioritize the importance of different variables in a complex data set.
Sankey charts are a great way to visualize data and make it more accessible to stakeholders, enabling them to more easily understand and use the data for decision-making.
In conclusion, Sankey charts are a powerful tool that can be used to visualize relationships and connections between different variables in data. They can be easily created using software, or can be done without any software. However, creating a Sankey chart also requires some understanding of data visualization and relationships between variables. So consider taking some time to read up on this topic and use your new skills to create the best possible dashboards and visualizations for your data journey.
