Watering the Garden of Thoughts: How Sankey Charts Visualize the Flow of Ideas

In the labyrinthine garden of thoughts, ideas sprout and intertwine in a complex tapestry of connections and influences. The journey of ideas is not just about their inception but also how they flow, merge, or diverge into new ideas or concepts. To navigate this intricate terrain, practitioners and enthusiasts in fields ranging from science and education to marketing and philosophy rely on a powerful tool—the Sankey chart. This unique graphing method brings to life the flow of concepts, data, and information, offering insights into the patterns and connections that often lie hidden in plain sight.

Understanding Sankey Charts

A Sankey chart is a type of flow diagram that represents the flux from one process or system to another. It presents the quantity flowing between two conditions with the thickness of the path (or “link”) representing the proportional quantity of each flow. This visual representation of the flow of information or data makes it easier to grasp the relative magnitudes of different flows and how they interact within a system.

Creating a Sankey Chart

Creating a Sankey chart is a straightforward process once you understand the basic components and steps involved. Here’s a simplified guide to help novices get started:

Identify the Direction of Flow: Determine the primary direction of movement for your data. This will dictate the orientation of your Sankey chart.
Collect and Arrange Data: Organize the data in a way that helps visualize the flow. This involves identifying the starting point(s), the middle processes, and the end destination or destinations.
Choose Your Software: There are many tools available for creating Sankey charts, including Microsoft Excel, Tableau, and specifically designed applications like RAWGraphs or Plotly.
Plot Your Data: Use the software you selected to input your data points and connections. Most programs will allow you to drag and drop data and adjust the thickness of each flow for proportional scale.
Customize and Add Context: Add labels to each source, step, and destination of the flow. This will help viewers understand what each flow represents. You can also change colors, widths, and add a title and description to create a more visually appealing and meaningful Sankey chart.

Applications of Sankey Charts

Sankey charts are versatile tools that can be applied across various domains. Some of the most common applications include:

Education and Research

Flow of Knowledge: Visualizing the dissemination of scientific knowledge across different disciplines or institutions.
Student Progress: Tracking the flow of students through different educational levels or majors.

Business and Economics

Supply Chains: Representing the flow of materials, energy, or goods within a supply chain.
Funding and Budgeting: Illustrating where and how much a company or organization allocates its resources.

Healthcare

Health Care Flow: Diagramming the pathway patients follow through the healthcare system (e.g., diagnosis to treatment to recovery).
Resource Use: Showing how resources within a healthcare system are allocated among different services or departments.

Social Media and Network Analysis

Viral Content: Visualizing how a message spreads through social media platforms and user networks.
Social Network Analysis: Representing the flow of information, products, or influence within a network of individuals or organizations.

Conclusion

Sankey charts are not just about representing data visually; they are about fostering understanding and insight. By providing a tangible visual depiction of the flow of ideas, data, and information, Sankey charts open the door to new perspectives, new insights, and a deeper appreciation for the interconnectedness of the world we live in. Whether used in a classroom, a boardroom, or a research lab, this visual tool is a gardener’s spade in the garden of thoughts, helping to cultivate and shape ideas into fertile realities.
