Why this is the answer
A Sankey graph visualizes the flow of data or resources between entities, with arrow widths proportional to the quantity or proportion moving from one node to another. In HubSpot, Sankey graphs help illustrate multi-step processes, conversion paths, or the distribution of leads and revenue across stages. This visualization highlights bottlenecks, major contributors, and relative flows within a system. It provides a clear, visual representation of relationships and proportional movement across multiple categories.
