The Dendrogram view will open showing a heat map with the hierarchical clustering results (Figure 4).

Samples are shown on rows and genes on columns. Clustering for samples and genes is shown through the dendrogram trees. More similar samples/genes are separated by fewer branch points of the dendrogram tree. 

...

Samples are now labeled with their Treatment group (Figure 5). 

Samples cluster based on treatment group and the 5μM and 10μM groups are more similar to each other than to the 0μM group.
