Blazor Sankey Chart Vertical Mode Example

This Sankey chart maps global coffee production and consumption in a vertical flow layout, tracing volumes from green‑bean varieties (Arabica and Robusta), through processing stages and product types, to regional demand centers. Link thickness encodes flow magnitude so throughput and losses are immediately visible.

Nodes represent discrete stages—variety, processing step, finished product, and destination region—while links show material transfer between those stages. The vertical orientation emphasizes upstream (production) to downstream (consumption) movement and simplifies visual comparison of stage‑by‑stage volumes and proportional splits.

Analysis capabilities:

• Hover over nodes to review production volumes and aggregated metrics at each stage.
• Inspect individual links to view exact transfer amounts and percentage shares between nodes.
• Follow link paths to understand production‑to‑consumption dynamics for a given variety or product.
• Visualize regional distribution to identify dominant markets and comparative demand patterns.

Use the chart to identify key flow patterns in the supply chain—major transfer routes, high‑volume processing nodes, and regional concentration of demand. Interactive hover and link‑tracing facilitate exploratory analysis, helping stakeholders detect bottlenecks, evaluate conversion yields, and compare relative contributions of Arabica versus Robusta across stages.

For implementation and examples, see the Sankey documentation: documentation section.
