What feature helps to visually represent spatial arrangements in diagrams?

The feature that helps to visually represent spatial arrangements in diagrams is 3D rendering. This tool provides a more immersive and realistic perspective, allowing users to view layouts and arrangements in three dimensions. By offering depth and perspective, 3D rendering enhances understanding of how different elements in a space relate to one another spatially. This can be especially useful in event planning, where the arrangement of tables, stages, or seating must be designed to ensure optimal flow and visibility.

While 2D views provide a flat representation of diagrams, which is useful for basic layouts, they lack the depth perception that comes with 3D rendering. A storyboard is primarily used for visual storytelling and planning sequences, which is not focused on spatial representation. Graphic overlays can enhance designs with additional information or branding but do not inherently provide spatial representation as effectively as 3D rendering does. Therefore, 3D rendering is the ideal choice for accurately depicting spatial arrangements in diagrams.
