FlowVisualize: The Alluring Aesthetic of Sankey’s Sanitary Secrets

Sankey charts have been a staple in the visual analytics toolkit for over a century, their distinctive design born from the visionary work of English engineer William Playfair and further refined by Scottish engineer Matthew sanction in the late 19th century. FlowVisualize, a testament to Sankey’s “sanitary secrets” in the realm of flow visualization, offers a fresh, intuitive way to perceive and analyze complex data where flows of energy, materials, or finance traverse various stages and systems. This article delves into the intricacies of Sankey chart creation and their versatile applications, highlighting the allure they’ve maintained across various disciplines.

The birth of Sankey diagrams

Sankey diagrams, also known as Sankey diagrams, are a type of flow diagram where the width of the arrows represents the quantity of the flow. They were originally developed to illustrate the energy flows in a process or machine, making it easy to identify where energy is lost as waste heat. The diagram’s unique aesthetic, where the width of the arrows changes as they move between levels, provides a quick visual comparison of process efficiency and waste management, particularly in the context of energy use in industries.

Crafting Sankey diagrams

Creating a Sankey diagram isn’t just about plotting data; it’s an art form that requires a keen understanding of the metrics you want to represent and your audience’s needs. Here’s a step-by-step guide on constructing one with FlowVisualize:

1. Define the Nodes and Flows: Start by identifying the main components (nodes) within your system and the quantities (flows) moving between them. Each node will act as a starting or ending point for an arrow.

2. Assign Direction and Width: The direction of flow should be logical, following the path of the energy, material, or money. The width of each arrow should correlate directly with the magnitude of the flow. FlowVisualize allows for dynamically adjusting the width to reflect the relative size of each flow based on your data.

3. Optimize Layout: As the diagram is constructed, the layout algorithm will attempt to arrange the nodes and arrows within the visual area. Fine-tuned positioning can enhance comprehension by grouping related nodes closer together or arranging them in a sequential layout that follows the natural flow.

4. Design for Clarity and aesthetics: Use clear, legible fonts and colors to enhance readability. The visual weight of the elements (e.g., broader flows in brighter colored arrows) must communicate scale and hierarchy effectively.

5. Add Labels and legends: Labels help identify each node or stream in the Sankey diagram, while legends interpret different colors and symbols to the audience.

Using FlowVisualize simplifies these steps with intuitive drag-and-drop interfaces and customization options that don’t compromise the beauty and effectiveness of the Sankey visualization.

Applications of Sankey diagrams

Energy Audit

Sankey diagrams are widely used in the field of energy audit to map and analyze energy flows in various systems, from buildings to entire power plants. FlowVisualize can help teams pinpoint inefficiencies and design corrective measures to reduce energy consumption.

Supply Chain Management

In logistics, Sankey charts can visualize the flow of products or components through a supply chain. This visualization might reveal bottlenecks, areas of excess capacity, and areas requiring improvement.

Environmental Studies

Environmental scientists use Sankey diagrams to illustrate emissions from different sources and the distribution of pollutants in ecosystems, providing a comprehensive look at the interconnectedness of environmental systems.

Finance

Financial institutions often use Sankey diagrams to visualize funds moving through investment pools or portfolio allocations. This helps in making better investing decisions by revealing pathways of capital and potential areas of higher returns and risks.

Process Optimization

Sankey diagrams are instrumental in process and manufacturing optimization. They help in understanding how resources are utilized in the production process, thus identifying where improvements can save costs and increase efficiency.
