Sankey charts are a powerful visualization tool for displaying complex flow data. They are particularly useful for presenting relationships between multiple entities and their interactions, making it easier to understand complex systems.
Sankey charts are named after Captain Matthew Henry Sankey, a British engineer who used this type of chart in the 1860s to represent the energy usage in a coal-powered factory. The design of Sankey charts consists of a network of arrows, each representing the flow of goods or resources between different entities, with the width of the arrows being proportional to the quantity of the flow.
The power of Sankey charts lies in their ability to make complex data simple and easy to understand. They display the total flow of resources between different entities, allowing you to visualize how much is going in and out, and where the most significant flows take place. By using color coding and labels, you can also categorize and label different flows, making it easy to see how the flow data is segmented.
Sankey charts have numerous applications in various fields. In the energy sector, Sankey charts are often used to visualize the energy flow from different sources, such as fossil fuels, renewable energy, and waste incineration, and how it is utilized in different sectors of the economy, such as transportation, industry, and residential. Sankey charts can also be used to represent other types of data, such as financial flows, traffic flows, and disease spread.
Creating Sankey charts requires a good understanding of data visualization principles and some level of technical knowledge. Several tools and software can be used to create Sankey charts, including Tableau, Microsoft Power BI, and R.
Tableau is a popular data visualization tool that allows you to create Sankey charts with ease. It includes a specific Sankey chart feature, which enables you to create stunning visualizations in minutes. Tableau allows you to customize the chart’s look and feel, including colors, labels, and shapes.
Microsoft Power BI is another popular tool that allows you to create Sankey charts. Power BI offers an intuitive interface and includes various templates that you can use to create your Sankey chart. Power BI also includes advanced features like drag and drop tools, animation, and interactive filters, making it easy to create dynamic and engaging Sankey charts.
R is a powerful programming language that offers various libraries and packages for creating Sankey charts. Tools like “ggridges” and “gganimate” offer advanced customization options that make it possible to create highly customized Sankey charts with animations and interactive features.
In conclusion, Sankey charts are a powerful visualization tool for displaying complex flow data, making it easier to understand and make decisions based on the data. Their wide range of applications makes them a valuable tool in various fields, including energy, finance, healthcare, and transportation, to name a few. Various tools and software are available to create Sankey charts, and with the help of these tools, you can create stunning Sankey charts that communicate your message effectively.
