Figure 4. Word Clouds demonstrating differences between overrepresented mutated pathways in lymph node-positive (a) and lymph node-negative (b) tumours.

The abstracted pathways (see methods) were plotted if present two or more times. The size of the words as well as the corresponding colours of the pathway names indicates the frequency of that abstracted pathway, and can be compared within and between the word clouds of each tumour subset.
