Frequently Asked Questions About AI Sankey Diagram Generator
Common questions and answers about our AI-powered Sankey diagram generation tool.
What is a Sankey diagram?
A Sankey diagram is a flow diagram where the width of arrows is proportional to the flow quantity. It's used to visualize energy flows, material transfers, budget allocations, and other quantitative flows between sources and destinations.
What types of flows can I visualize?
You can visualize any quantitative flow including energy flows, budget allocations, material flows, customer journeys, web traffic, supply chain flows, and resource distribution.
How does the AI calculate flow widths?
The AI analyzes the quantities you provide and automatically calculates proportional widths for each flow, ensuring that larger quantities are represented by wider flows for easy visual comparison.
Can I use these diagrams in reports?
Absolutely. All Sankey diagrams generated by our AI tool are free to use in sustainability reports, business presentations, research papers, and any commercial or non-commercial projects.
