Amigas are particularly well suited to vector plotting because the polygon acceleration of the Amiga chipsets can plot polygons with more than 3 or 4 vertices and fill them with patterns or solid colors without too much overhead.

The CPU still has to do a lot more work figuring where the vertices go and how many to render.  Especially hard is the fact that Graphics.library doesn't have a bezier curve-plotting function.

Outline fonts are a perfect example of vector images.  The vertices may be located on an 8x12 grid but will scale up to 48x60 pixels without effort.  The downside of the Amiga font engine is that colorfonts must be bitmapped fonts and all existing outline fonts are monochrome.
