Sankey charts: Unlocking the Visual Power of Data Storytelling with Flow Charts
In the realm of data visualization, there exists a powerful and captivating tool that not only presents complex information in a visually compelling manner but also helps to understand the flow and patterns within the data – the Sankey chart. This visual magic is designed to unravel the interdependencies and relationships, making complex data processes accessible and understandable for all. By exploring the principles and applications of Sankey charts, we can unlock their full potential to tell compelling stories with your data.
What are Sankey Charts?
Sankey diagrams, also known as flowcharts or sequential flow diagrams, are a type of network diagram that depicts the quantity or quantity flow of a resource or any other variable from one state to another. They were initially developed in the mid-19th century by William Thompson, a British engineer, for depicting the flow of energy and materials in industrial processes. The most notable feature of Sankey charts is their vertical arrows that represent the volume or flow of data, allowing readers to instantly grasp the amount and direction of movement within the data set.
Key Features of Sankey Charts
-
Volume and Direction: Central to the Sankey chart is the emphasis on the quantity and direction of the flow, which is indicated by the size of the arrows and their orientation. This clear representation is particularly helpful in illustrating the flow from one step to the next, revealing the relationships between different processes or inputs.
-
Hierarchical Structure: Sankey charts capture the hierarchical structure of data, making it ideal for showing the flow between multiple levels or categories. This becomes particularly useful when analyzing processes or systems with multiple branches and sub-processes.
-
Comparison: The cumulative nature of Sankey charts enables easy comparison of flows across different pathways or segments. This is particularly useful for highlighting variations, differences, or dependencies between channels.
-
Ease of Understanding: Due to their linear and intuitive design, Sankey charts are generally easy to comprehend, even for those with little prior knowledge of data visualization. This makes them a valuable tool for non-technical audiences as well.
Application Scenarios
-
Energy Analysis: Sankey charts are commonly used in the field of energy to demonstrate the flow of fuel from production to consumption or the distribution of power within a grid.
-
Resource Allocation: Sankey charts can illustrate the allocation of funds, resources, or personnel in various projects or departments, highlighting the allocation and distribution to ensure transparency.
-
Supply Chain Analysis: They are particularly effective in tracking the movement of goods and services in the supply chain, revealing bottlenecks, inefficiencies, and dependencies.
-
Environmental Impact: Sankey charts help visualize the reduction or increase in greenhouse gas emissions, helping policymakers understand how changes affect the environment.
-
Process Improvement: By examining the flow of data in a process, Sankey charts can pinpoint areas that require optimization or highlight potential improvements.
