Title: Sankey Chart Creation and Applications: Exploring the Power of Visualization Techniques for Analyzing Complex Data Flows.

Introduction

Visualization techniques play a vital role in helping organizations and individuals interpret complex data flows. Sankey charts are one such visualization method that makes it possible to visualize data flows in a more intuitive and easy-to-understand manner. This article aims to explore the practical applications of sankey charts and delve into their creation process.

Sankey chart visualization

Sankey charts are a type of diagram that depicts data flows with arrows. The chart typically includes three types of data points: source, destination, and each edge of the chart represents a flow between these points. The width of the arc representing the flow indicates the amount of flow.

One of the applications of sankey charts is in business analytics for resource allocation and budgeting. Sankey charts can be used to show how different resources (such as money, personnel, or time) are allocated between departments or between departments and the outside world. This enables managers to visualize their department’s budget and where changes in resources (such as layoffs or budget cuts) can have the most impact.

Another important application of sankey charts is in environmental tracking. For example, climate tracking networks use sankey charts to show the flow of carbon emission from energy sources to the atmosphere. This is important information for policymakers to understand the impact of changing policies on atmospheric carbon levels.

Creating a sankey chart

A typical sankey chart consists of an axis for measuring time, an axis for measuring quantity (such as amount or amount spent), and a diagram displaying the flow of data. This diagram can be represented graphically on a paper or on a computer screen.

In creating a sankey chart, the following steps can be taken:

1. Collect relevant data.

2. Determine the source, sink, and arrows that represent each point in the flow.

3. Create the diagram. Typically, the source and sink are indicated with a circle, while arrows show the direction of flow:

   • Each arrow arrow represents flows

   • The width and position of the arrow suggest the amount of flow.

   • The length of the arrow represents the duration of the flow, and it can be adjusted for flow rate.

4. Label axes and the diagram clearly.

5. Add labels and details indicating the meaning of the flow arrows.

6. Optionally add annotations showing the direction, duration, and amount of the flow.

Conclusion

Sankey charts are a powerful and flexible tool for analyzing complex data flows. By visually displaying data flows, sankey charts make it possible to see trends and outliers, and understand how resources are allocated and managed within a particular system. Sankey charts can be used in a range of applications, from business finance to environmental tracking, making them a valuable and frequently used visualization tool.
