I don't think a graph is necessary. Beacuse you are supposed to get one viability count for one particular sample. However, if you have more than one sample, for instance, soil samples from multiple places, then you can make a graph using Microsoft Excel or graphpad prism. For a graph you need multiple samples to compare.
