Sankey charts are an indispensable tool for visualizing the flow of quantities between interconnected nodes. Known for their unique, visually stunning appeal, Sankey diagrams have caught the attention of data analysts, designers, and researchers worldwide. In this article, we delve into the core principles of creating impressive Sankey charts, explore their various applications, and uncover some fascinating Sankey chart stories that can inspire you in your data visualization projects.
Principles of Sankey Chart Creation
Sankey charts work by representing flows of quantities between nodes, where thicker arrows denote larger flows. To create effective Sankey diagrams, consider the following best practices:
Data Preparation
- Identify Flow Quantities: Collect data on the quantities flowing between different categories or nodes. This data might come from various sources, such as sales figures, energy consumption, or financial transactions.
Choosing the Right Layout
- Layout Optimization: Optimize the layout to ensure that the chart is comprehensible and aesthetically pleasing. Avoid overcrowding nodes and keep the chart’s overall structure clear.
Color Scheme Selection
- Color Consistency: Use consistent colors for the same node types or categories to maintain clarity and support the reader’s understanding of the flow patterns.
Interactive Features
- Enhance Interactivity: For complex data sets, consider adding interactive features such as tooltips, zoom capabilities, or hover effects that allow users to explore the data in more detail.
