I am looking at this graph that shows axis one and two without any data table for the species and locations. In the table itself six physical locations are spread about at different spots and twenty or more species also spread about, more accurately they are clustered. There are also some lines drawn around the clustered data (location and species) while other data (location and species) are outside of the area. Any quick explanation is very appreciated.
