Polygonal glyphs can have many different geometries. The glyph itself is a polygon or a polygonal object in 2 or 3 dimensions. Certain characteristics of the glyph are data-driven (such as size, color, orientation, etc.).

Below we see an example of a polygonal glyph visualization. At each point in the volume, a sphere is placed. The size of the sphere is determined by a scalar value at that point.
