The horizontal position on the plot to display the current level of the dendrogram.
The range of values in which the current level of the dendrogram will be displayed.
A flag for the function to know whether it is at the top level of the dendrogram or not. Do not change this argument.

furc displays one furcation of the dendrogram. A furcation is a single box displaying its label and count that may split into finer divisions. If so, furc calls itself for each furcation until there are no more splits.
On the final level of categorization, the category labels are staggered to minimize overprinting.
