Sankey charts are a powerful visualization tool that allow users to explore and analyze the flow of resources, information, or other entities within a system. These charts are named after their creator, Scottish engineer Captain John Snow, who used a similar diagram to map the cholera outbreak in London in the 19th century. Today, Sankey charts are used in a wide range of fields, from energy systems to data flow in websites, and can provide deep insights into the underlying patterns and relationships within complex systems.

Creating a Sankey chart involves a few key steps. First, the user must identify the source, sink, and intermediate nodes in the system being visualized. For example, in an energy system, sources might include renewable energy sources like solar and wind, while sinks might include end-use applications like heating, lighting, or transportation. Intermediate nodes might represent energy storage systems or conversion technologies. Next, the user needs to quantify the flow between each node, typically by assigning a value to the link width that represents the magnitude of the flow. Finally, the user can choose a layout algorithm that best represents the flow patterns and highlights any important features, such as bottlenecks or major transfers.

Applications of Sankey charts are numerous and varied. In energy systems, they can be used to visualize the flow of electricity from power plants to end-use applications, helping to highlight inefficiencies and identify potential areas for improvement. In manufacturing, they can be used to map the flow of materials through a production line, helping to identify waste and streamline processes. In data analysis, Sankey charts can be used to visualize the flow of information or traffic across websites or social networks, helping to identify patterns in user behavior and inform design decisions.

Another key feature of Sankey charts is their ability to provide context and nuance to the data being visualized. By mapping the flow of resources or entities, Sankey charts can help users understand not just the quantity of a flow, but also its direction and context. They can also be customized to highlight specific aspects of the flow, such as the efficiency of a particular source, the contribution of a particular sink to overall output, or the impact of a specific technology or policy on the flow.

Overall, Sankey charts provide a powerful tool for exploring and visualizing complex flow systems. By mapping the flow of resources, information, or entities within a system, users can gain a deeper understanding of the underlying patterns and relationships, and make more informed decisions based on that understanding. Whether used in energy systems, manufacturing, data analysis, or any other field, Sankey charts provide a powerful way to visualize and communicate complex systems and flows, unlocking new insights and opportunities for innovation.
