Flowing Ideas: The Story Behind Sankey Charts and Their Creative Applications
In the vast landscape of data visualization, one chart has managed to stand out for its unique ability to depict data in a flow-like manner. Introduced by William Sankey in 1899, the Sankey diagram, or Sankey chart, is a powerful visualization tool that illustrates the direction and quantity of data flow from one step to the next. These charts are not merely about visualization; they are a testament to the creative and analytical minds that have applied them across various fields.
The Creation of Sankey Charts
Sankey diagrams have their roots in William Sankey’s work on steam engine efficiency. In 1899, Sankey used these diagrams to illustrate the energy losses in steam engines, effectively demonstrating the efficiency of steam engines through a visual representation of the input and output energies. This work would pave the way for the popularization of these charts, not only for their effectiveness in conveying complex data but also for their flexibility in applications.
Creative Applications of Sankey Charts
The versatility and unique nature of Sankey diagrams have led to a wide range of applications, from scientific research and energy management to economics and social media analysis. Here are a few intriguing ways in which Sankey charts have been creatively applied:
1. Environmental Science and Efficiency Analysis
The original application of Sankey diagrams, environmental scientists and engineers use these charts to determine the efficiency of processes. In renewable energy and waste management, Sankey diagrams map the flow of materials and energy, highlighting losses and opportunities for improvement.
2. Economic Analysis
Studying the flow of goods, money, or inputs across different sectors, Sankey diagrams allow economists to visualize economic activity. This includes analyses of trade flows, the economic consequences of public investment, or the impact of globalization on local economies.
3. Social Media and Data Analytics
In the digital age, Sankey diagrams are increasingly used for data analysis and visualization. They help in understanding the flow of information, influence, or engagement across social networks. For instance, they can visualize the spread of memes, the popularity of influencers, or the flow of funds through P2P (peer-to-peer) lending platforms.
4. Transportation and Logistics
Transport companies and urban planners use Sankey diagrams to map out the flow of traffic, goods, or passengers. This includes analyzing the efficiency of logistics, assessing the impact of new transportation routes, or even planning urban development.
5. Scientific Research and Publications
In scientific research, Sankey diagrams are employed to visualize the flow of scientific knowledge, collaborations, or citations. Studies often use these charts to see connections between fields, influence of a particular study, or the evolution of research over time.
The Creative Process Behind Sankey Diagrams
Crafting a Sankey diagram involves several steps, including gathering and organizing data, selecting the right tool, and then creatively arranging the data flow in a visually compelling way. Each segment of the flow represents a percentage of the total data, making it crucial for the creator to understand the data’s significance and how to highlight its flows effectively. The final product is not just informative but also engaging, encouraging viewers to appreciate the data’s depth and complexity in a new light.
Conclusion
Sankey diagrams, with their ability to capture and convey complex flows of data visually, continue to evolve and innovate across various fields. From energy efficiency to social media analysis, these charts remain a powerful tool for creative visualization. The story of Sankey charts is not just about a chart type but a testament to the creative approaches and insights that data visualization techniques like the Sankey diagram can bring to the forefront. As data becomes more prevalent and complex, the role of visual storytelling will become increasingly significant, and the Sankey chart will likely remain a key player in the field.
