Sankey charts are a type of flow visualization chart that are used to represent the flow of a quantity between different nodes or categories. They are named after Captain John Snow, who first used a similar type of diagram to study the cholera outbreak in London in 1854. The chart is essentially a flow story that provides a visual narrative of how the quantity is distributed and moves through different categories or nodes.
Creating a Sankey chart involves a few basic steps. First, you need to define the nodes or categories that you want to represent in your chart. This could be any type of data, such as countries, industries, or countries of origin. Next, you need to define the flow or quantity that you want to represent. This could be any type of data that involves movement or transfer between the nodes, such as money, people, or energy. Finally, you need to connect the nodes and flows together in a way that visually represents the flow of the quantity between the nodes.
There are many applications for Sankey charts, particularly in fields that involve studying flows or distributions of data. For example, Sankey charts can be used to visualize the flow of energy through a power grid, the flow of traffic between different locations, or the flow of financial transactions between different countries or regions. They can also be used to visualize the flow of resources within an organization, such as the flow of materials between different departments or the flow of employees through different stages of a project.
One of the key benefits of Sankey charts is their ability to provide a visual narrative of the flow of data between different nodes. This can help users to quickly understand and interpret complex data sets, as the chart provides a clear and concise overview of the distribution and movement of the quantity. Additionally, Sankey charts can be used to highlight important trends or patterns within the data, such as the sources and destinations of the flow or the largest contributors to the flow.
Flow stories can also be created with Sankey charts to provide a more engaging and interactive experience. By telling a story through the visual narrative of the chart, users can gain a deeper understanding of the data and its context. For example, a flow story could be used to explain the flow of trade between different countries over time, highlighting the biggest opportunities for growth and the challenges that need to be addressed to maintain a stable flow of trade.
Overall, Sankey charts are a powerful tool for visualizing and understanding the flow of data in a variety of contexts. By creating flow stories with Sankey charts, users can unlock the full narrative power of these charts and gain valuable insights into complex data sets.
