You can draw different animated lines with line styles and effects in Fusion. The Fusion paint node has some powerful options to create interesting lines and shapes. You can use custom brushes, adjust the spacing and more.
To get even more options, you can combine multiple paint strokes together by reusing the underlying polyline within the modifier or you can manipulate your drawing with additional effects.
Finally, you can create very interesting lines by combining drawings with particle effects from the Fusion Particle tool set.
