These charts are not that useful unless there's a comparison. This one in particular is problematic because the first 2 ranks sum to far more than 1...and since the graph is to represent proportional abundance of each species, the entire graph should sum to 1.
The reason this graph sums to more than one is it is not actually plotted on a log scale. Look at figure 8 here to see how it should be done https://www.nature.com/scitable/knowledge/library/sampling-biological-communities-23676556/
