The Briqlab Flow Sankey is a free Power BI custom visual for analysts who need to show not just where a quantity ends up, but how it gets there. Flow width encodes volume — the wider the band, the more value moves through that path — so stakeholders immediately see which routes dominate, where flow splits, and where it converges, without reading a single number. It is the only visual type that answers "where does everything go?" and "how much is lost at each stage?" in the same diagram.
• Dynamic flow width encoding — band thickness scales proportionally to value
• Multi-level rendering — supports up to five flow stages in a single canvas
• Automated node colour-coding with a configurable category palette
• Interactive path highlighting — click any node to isolate its inflows and outflows
• Value annotations displayed directly on flow bands for at-a-glance reading
• Configurable node width, padding, and link curvature for layout control
• Interactive tooltips showing source, destination, and flow value on hover
• Cross-filter interaction with other visuals on the report page
• Dark and light theme compatible with no extra setup
• Budget distribution — trace spend from top-line budget through divisions to projects
• Customer journey mapping — volume moving through acquisition, activation, and retention stages
• Energy and resource flow — input sources through conversion steps to end uses
• Sales funnel analysis — leads flowing from source through pipeline stages to closed won
• Organisational restructuring — headcount movement between departments or locations
