What effect style is applied to a SmartArt diagram for more visual impact?

The choice of Intense Effect style for a SmartArt diagram is aimed at enhancing visual impact. This style incorporates deeper colors, added shadows, and sometimes 3D effects, which collectively draw the viewer's attention to the diagram more effectively than other styles.

Using Intense Effect makes elements within the diagram stand out, thus enhancing readability and helping to convey the intended message clearly. This style is particularly effective in presentation scenarios, where the goal is to communicate information compellingly and memorably.

In contrast, other styles like Classic Style, Bold Style, and Simple Effect may not provide the same level of visual engagement or dramatic impact as Intense Effect. Classic Style tends to maintain a traditional and understated appearance, while Bold Style focuses on strong, noticeable features without the additional visual enhancements found in Intense Effect. Simple Effect is quite minimalistic and may lack the richness that can help capture an audience's attention.
