The heat map view

The tool generates a heat map showing the abundance of each feature in each sample and showing the sample clustering and/or feature clustering as a binary tree over the samples and features, respectively (figure 7.15).

Each column corresponds to one sample, and each row corresponds to a taxon. Samples and features are hierarchically clustered. Available sample metadata is added as an overlay.
