Sankey charts are a powerful tool for visualizing flows and relationships within data. These charts use unique node and link diagrams to represent complex systems, making them highly effective for various industries, including data science, economics, energy systems, transportation networks, healthcare, and more.
What is a Sankey Chart?
A Sankey chart is a type of flow diagram that represents values or quantities being transferred from one variable to another. This is achieved by using nodes to represent variables and links (or arrows) to indicate the flow or transfer between those nodes. The width of the links is directly proportional to the volume of data they represent, allowing viewers to visually understand patterns and correlations easily.

Key Features of Sankey Charts

1. Data Transfers: They excel at showing how values move between different states, compartments or flow streams in an attractive and easy-to-understand format.
2. Flow Visualization: Sankey charts make it simple to visualize pathways by linking together components with arrows that branch out like real pipes or flows in an actual network.
3. Comparison Capacity: They allow for the comparison of different quantities or values simultaneously through various link widths.
4. Customizability: As one can easily color-code, style nodes and arrangement layouts to provide deep insights into your data.

Applications of Sankey Charts

1. Energy Systems Analysis
   Understanding energy flows in power grids or distribution channels helps utility companies optimize efficiency and identify potential inefficiencies or bottlenecks.

2. Data Science Research
   In AI training process analysis, Sankey charts highlight the inflow/outflow of data across different layers, aiding researchers in improving model performance.

3. Business Workflow Analysis
   Visualize internal business processes like marketing campaigns’ impact on sales funnels to optimize resource allocation and enhance operational effectiveness.

4. Transportation Networks
   Identify efficient routes versus congested ones based on passenger or cargo movement; crucial for urban planning and logistics optimization.

5. Healthcare Management
   Display patient pathways through diagnostic procedures to facilitate better resource management, particularly in tracking treatment response rates across clinics.

6. Economic System Modeling
   Illustrate financial transactions between sectors (e.g., government spending vs investment) for better fiscal policy-making decisions at national and international levels.

How to Create a Sankey Chart

Creating a Sankey chart involves several key steps:

1. Define Your Objective:

Identify the specific variable(s) you’re tracking across different nodes.

2. Gather Data:

Collect comprehensive data related to your flow; this could include numeric values (amounts transferred), timestamps (timeline for each transfer), identifiers (unique labels for sources and destinations).

3. Select Software or Library:

Depending on your project requirements (platforms typically vary), choose an appropriate software such as Tableau Desktop & Online Version (UI-based) for simplicity or Python libraries such as plotly or networkx (for code-based development).

4. Create Nodes:

Define nodes that will serve as input points in your network – remember each will get its own unique position in your visualization if it’s dynamic.

5. Map Flows:

Plotter flows based on volumes – ensure smooth transitions between respective nodes with correct arrow widths indicating scale/amount volume moving from source node(s) towards destination node(s).

6. Apply Style Customization:

Modify links’ colors and opacity levels matching thematic aspects such as increasing scale sizes reflecting higher volume movement over time/dates if applicable e.g., blue-to-red transition indicating rising/falling growth trends over past years/more recent changes respectively).

7. Inspect & Iterate:

Analyze rendered outputs ensuring ease of understanding from first glance while facilitating deep dives into individual branches requiring detailed examination; fine-tune aesthetics along with interpretative insights accordingly refining output until satisfied outcomes achieved reflecting crucial relationships accurately portrayed convincingly).
