Minimum spanning trees showing spa types in each of the states. Each circle with different color represents spa type and size of the circle indicates the number of isolates for a particular spa type. Major spa type in each state is highlighted by a grey halo around the circle. The branch thickness (dotted lines, dashed lines and increasing thickness of solid lines in that order) indicates inverse of the distance between the types.
