In today’s age of data-driven decision-making, visualizing complex data flow through charts and diagrams has become essential. Sankey charts are one such visual tool that helps to analyze relationships between different entities and represent the flow of data through them. In this article, we will unlock the mysteries of sankey charts and master the art of visualizing complex data flow.
Introduction:
A sankey chart is a type of line chart in which the flow of data is represented as a series of arrows or lines. Each arrow represents a component that is receiving or sending data, and the length and color of the line indicates the quantity and direction of the flow.
Sankey charts are widely used in various fields such as engineering, economics, social sciences, and data science. They are particularly useful in visualizing how different entities are interconnected and how data flows between them.
Creating sankey charts:
The process of creating sankey charts can be divided into two main steps: data collection and chart design.
Data collection:
The first step is to collect the data for visualization. This data should be organized in a way that makes it easy to understand the flow of data. For example, if you have a dataset of transactions between different entities, you can use this data to create a sankey chart.
Chart design:
The second step is to design the chart. This involves selecting the appropriate type of sankey chart, deciding on the colors and shapes for the nodes and edges, and deciding on the layout.
Types of sankey charts:
There are two main types of sankey charts: the source and destination sankey chart and the flow sankey chart.
- The source and destination sankey chart represents the flow of data from one node to another, with the nodes and edges representing the source and destination nodes respectively.
- The flow sankey chart represents different components with different colors and shapes, with the arrows representing the direction of flow.
Applications of sankey charts:
Sankey charts are widely used in various fields, including:
- Marketing: To visualize the flow of customer data and track the impact of different marketing campaigns.
- Engineering: To visualize the flow of data in the engineering industry, especially for the analysis of project costs and schedules.
- Social sciences: To visualize the flow of ideas and information between different entities, such as the flow of ideas in a university research seminar.
- Data science: To visualize the flow of data in data analysis and machine learning workflows.
Conclusion:
Sankey charts are an effective visual tool for analyzing complex data flow. By collecting the correct data and using the appropriate chart type, you can create insightful and visually appealing representations of the flow of data between different entities. With the right data, sankey charts can reveal patterns and relationships that may not be immediately apparent through traditional data visualization techniques. By mastering the art of sankey chart creation and applications, you can gain valuable insights into complex data flows and make data-driven decisions with confidence.
