Flowchart in Fashion: Decoding Data with Sankey Sensations

In the world of fashion, as in any industry, data plays a pivotal role in informing decisions, predicting trends, and optimizing processes. Among the many tools data scientists and analysts use is the Sankey diagram, an under-the-radar visualization technique that has gained traction in industries that benefit from the decoding and representing of the flow of materials, energy, or information. Enter “Flowchart in Fashion,” where Sankey diagrams transform the dynamic nature of fashion decision making into an easily digestible, visually appealing format. This article delves into the world of Sankey chart creation and applications in fashion.

Understanding Sankey Diagrams

At their essence, Sankey diagrams are flowcharts that visualize the workflow of a system by showing inputs and outputs in streams that start wide and narrow based on the magnitude of the flow. The diagrams’ namesake is Victorian Engineer Henry Darcy, though their modern form was popularized in the early 20th century by Mining Engineer Max Maximilian and Engineers in industries such as power stations.

Sankey diagrams use arrows to depict flows while varying their widths and lengths to reflect the quantities flowing. By visually summarizing large amounts of complex data on a single chart, they offer a comprehensive, easy-to-understand summary of a process’s efficiency.

Sankey Diagrams in Fashion

In the fashion industry, such visualizations serve multiple purposes:

1. Understanding Material and Resource Flows

In fashion, goods flow through an elaborate supply chain, from raw materials to production and distribution. Sankey diagrams can illustrate where resources are used, wasted, or conserved, offering a clear look at efficiency and pointing out potential for improvement.

2. Decoding Consumer Trends

Fashion analytics utilizes Sankey diagrams to visualize consumer behavior and trends over time. This analysis can include flow information like the rise and fall of styles, the movement of inventory through retail spaces, or even the flow of influence from social media to consumer spending.

3. Sustainable Fashion Initiatives

With environmental concerns increasingly shaping the fashion industry, Sankey diagrams are instrumental in mapping sustainable initiatives. These diagrams can visualize the impact of sustainable choices, such as the use of organic materials or reduced water consumption, all while providing a snapshot of overall environmental footprint.

4. Predicting and Optimizing Future Trends

Fashion is an industry that must predict and adapt quickly to market demands. By analyzing historical sales and inventory flow, industry professionals can use Sankey diagrams to anticipate future trends easier and optimize their operations accordingly.

Sankey Chart Creation

Creating a Sankey chart involves the following steps:

1. Collect Data: Begin with data related to the process you’re visualizing. This might include quantities of materials, levels of energy consumed, or even the intensity of social media interaction.

2. Define System Boundaries: Decide the start and end points of your process. All flows start and end at these boundaries.

3. Create Nodes: Nodes represent activities, processes, or states in your system. Place nodes at strategic points along the flow lines.

4. Draw Paths: Lines represent the flows of materials, energy, or information through the system. They should be scaled to reflect the magnitude of the flow.

5. Adjust Widths and Lengths: Make sure that the width of the arrows increases with the amount of material, energy, or information transferred, providing an indication of the size of the flow.

6. Add Labels and Titles: Use labels and a title to give context to the Sankey diagram, explaining what it represents and how data is represented.

7. Interactivity: If sharing the charts with others, opt for interactive versions that allow for clickable elements, providing a deeper interpretation of the data.

Sankey Diagram Software and Tools

Several tools and software packages are available for creating Sankey diagrams, each with different strengths:

• Sankey Diagrams by Microsoft Visio: Incorporates Sankey diagram functionality within its comprehensive drawing software suite.
• Sigma.js: A JavaScript library specifically designed for creating interactive Sankey diagrams.
• Gephi: While primarily a network analysis platform, it offers Sankey diagrams as part of its visualization toolkit.
• Python’s SankeyLib: An open-source Python library for generating Sankey diagrams from data.

Conclusion

Sankey diagrams offer valuable insights into the complex interplay of materials, resources, and energy in fashion, among other industries. With increasing demand for sustainability, efficiency, and consumer understanding, these diagrams serve as a vital tool in the fashion analyst’s toolkit. By creating intuitive, detailed visuals, they help in making more informed decisions, influencing trends, and ensuring a more sustainable future for the fashion world.
