Can I make graphs or do heavier data analysis?

Once you've selected a site, you'll see an "Analysis and Graphs" link near the top (as shown below).


Clicking on this link will get you to the graphing page, shown below left. By default, this will show a graph of species richness (native in green, non-native in brown) broken down by plot within the site you've selected. Other graph types and/or options can be selected directly below the graph in the "graph options" section (as shown below right).
