Figure 2: Correlation network of microbiota resident on the scalp.
From: Dandruff is associated with the conjoined interactions between host and microorganisms

Each node shows one genus of bacteria or one species of fungi. The size of the node corresponds to the log-transformed relative abundance of the microbiota. The thickness of the edges corresponds to the |r| value of the Kendall relationship. The color of the edges corresponds to the positive (red) or negative (blue) relationship. The length of the edges has no meaning.
