This is a mixture of elements. Each different circle is one type of element. Because there are two different colors and none of them form compounds that means this is a mixture of two different elements.
Example Question #52 : Elemental Composition Of Pure Substances
Each circle represents an atom and each different color represents a different kind of atom. If two atoms are touching then they are bonded together as a compound.
