-The DevExtreme JavaScript Pyramid Chart is often used to visualize an organizational structure. In this demo, the pyramid displays a team’s composition, reflecting both subordination and strength. In code, the pyramid is created using the Funnel component with the **algorithm** property set to _«dynamicHeight»_ and **inverted** property set to **true**.
