Visualization of evolution of communities generated by the Louvain [5] method using the Netgram tool for the Big dataset.

<p>We can observe significant events like merge, split, death and shrinkage of communities. For example, we can observe the split of communities <b>C7</b> and <b>C8</b> at time-stamp T₂ and T₃ respectively. Similarly, we can observe a merge event for cluster <b>C1</b> at time T₄. We observe a general pattern of shrinkage for most of the communities in this dataset.
