Explain the common use of speed lines and visual effects in manga and how they contrast with their usage in comics.

Manga heavily utilizes speed lines, motion lines, and other visual effects (like sweat drops, thought bubbles with exaggerated expressions) to convey action, emotion, and internal states. While comics also use these, manga tends to employ them more frequently and with a greater emphasis on stylized exaggeration. Comics often integrate these effects more seamlessly into the overall artwork.
