Sankey charts are a type of graph used to visualize flows, such as energy or water usage, material or financial transactions, or anything that can be quantified and tracked. Unleashing the power of Sankey charts involves not only understanding their creation but also their diverse applications in various industries.
Creation of Sankey Charts
Step 1: Identify the Data
The first step in creating a Sankey chart is to identify the data that you want to visualize. This data should contain information about the origin, destination, and quantity of flows.
Step 2: Determine Flows and Nodes
Decide how the data should be categorized. The most common way is by creating “nodes” that represent the sources and destinations of the flows. Each node is connected by “links” or “arrows” that represent the flow of material, energy, etc., between them.
Step 3: Normalize the Flux
The size of the links represents the magnitude of the flow. Make sure to normalize the data if the sizes vary widely, so as not to distort the visual impact of the chart.
Step 4: Choose a Visualization Tool
There are various tools available for creating Sankey charts, including software like Microsoft Office, QGIS, and specialized libraries such as Plotly or D3.js for web-based charts.
Step 5: Design and Style Your Chart
Design your chart to ensure clarity and aesthetic appeal. Consider using color coding for different sources and destinations, and make sure the chart isn’t overcrowded so that all flows are readable.
Applications of Sankey Charts
1. **Environmental and Energy Studies
Sankey charts are invaluable in visualizing the flow of energy or environmental resources. For instance, they can show the distribution of renewable energy sources between countries or the breakdown of energy consumption within a city.
2. **Process Engineering and Manufacturing
In process engineering, Sankey charts provide a clear view of material flow within production processes. This insight helps in identifying inefficiencies and areas for improvement.
3. **Marketing Attribution
Sankey charts can be used to track the effectiveness of marketing channels by showing the flow of leads from one channel to another, ultimately leading to a sale.
4. **Economics and Finance
Economists and financial analysts use Sankey diagrams to understand the flow of money or trade between different regions or sectors, helping to pinpoint the most significant transactions or trade deficits.
5. **Healthcare
In healthcare, Sankey charts can track the flow of patients through different stages of treatment or the movement of patients between healthcare facilities.
Unlocking Insights
What truly sets Sankey charts apart is their ability to reveal patterns, trends, and disparities that are not as apparent in tabular data or more conventional charts. They make complex data easy to understand by visually showing flow dynamics, making them an indispensable tool for data storytelling and decision-making.
In conclusion, whether you’re a scientist, engineer, business analyst, or economist, harnessing the power of Sankey charts can open up new perspectives on your data. By creating effective Sankey charts tailored to your specific needs, you can communicate your findings clearly, highlight key trends, and aid in making informed decisions.
