Sankey charts are a valuable tool for visualizing complex data in a clear and concise manner. They are particularly useful for representing relationships between different elements or flows, and can reveal important underlying patterns and trends. In this article, we’ll explore the power of Sankey charts and provide a quick and informative guide on how to create and apply them.
Understanding Sankey Charts
Before we dive into specific examples of Sankey charts, it’s important to understand the basics of the chart type. A Sankey chart consists of two or more lines connected with arrows. Each arrow represents a different element or flow, and the length and direction of the arrows indicate the flow rate. For example, a Sankey chart could show how different water flows through a city’s infrastructure, with each arrow representing a specific source (e.g., a water treatment plant) and destination (e.g., the city’s infrastructure).
There are a number of different types of Sankey charts, each with its own design and layout. Some common types include directed flow, bidirectional flow, and two-way flow. Each requires slightly different techniques for creating and interpreting the data.
Applying Sankey Charts
Sankey charts are well-suited for visualizing complex data, and can be used in wide range of fields, such as transportation, water resources, and environmental management. Here are a few example applications of Sankey charts:
Transportation management: Sankey charts can help identify bottlenecks and improve efficiency in transportation systems. For example, a Sankey chart could show the flow of vehicle traffic between different highways, allowing for real-time monitoring of traffic flow and the optimal routing of vehicles.
Water resources management: Sankey charts can be used to visualize water flows through a city’s infrastructure, helping to identify inefficiencies and potential problems. For example, a Sankey chart might show the flow of water through a city’s water treatment plants, allowing for real-time monitoring of treatment output and identifying areas for improvement.
Making Sankey Charts
Here are some tips for creating and applying Sankey charts:
Choose the right type of Sankey chart: Depending on the type of data and the desired visualization, you may need to choose between a single-line, two-line, or multi-line Sankey chart. Consider the layout and placement of the elements and arrows, as well as the length and direction of the arrows.
Ensure a clear and concise design: A well-designed Sankey chart should be easy to understand. Avoid clutter and unnecessary elements, and ensure that the elements and arrows are clearly visualized.
Visualize important patterns: Sankey charts can reveal important patterns and trends in data. Use them to highlight any unusual or significant flows, and use annotations and labels to further clarify the meaning of the graph.
Conclusion
Overall, Sankey charts offer a valuable tool for visualizing complex data and revealing important underlying patterns in data. By choosing the right type of chart, ensuring a clear design, and visualizing important trends, you can use Sankey charts to gain valuable insights and make informed decisions.
