Cellular hierarchies. Three hierarchically related clustering structures for a single cell mouse neuronal dataset [27]. The data has been projected on to the first four principle directions, we report the three that allows best data visualisation; we used the given cellular labels to colour cells according to the a 4, b 8, and c 11 cell subtypes identified in the original study
