Newbie's doubt regarding fancyRpartPlot - Titanic: Machine Learning from Disaster

Realize this is an older thread, but need to correct the explanation from Ram, as it is not correct. I noticed this using the Wine data set available here. The resulting plot is attached. The way to interpret the plot is that each class of V1 (1, 2, or 3) corresponds to a different color in the plot. Each square is a node.
