how to censor data point labels (annotations) if label text overlaps in the plot when using ggraph

Time:06-06

I am attempting to plot some data using ggraph. The style is a circular partition plot. I have numerous plots/graphs. Each has a different density of dendritic branching. Nodes on the graph are labeled with geom_node_text(aes(label = labelText)). I know I can use scaling or text size to adjust effective font point. However, I would like to hold font point constant and just censor labels (i.e., assign label value to be something like " ") for dense regions of each graph, given some density threshold parameter. How could this be done? For instance, is there a way to extract the x, y coordinates of text labels such that a density function can be computed over the plot area?

This falls under the heading of RTFM.

check_overlap
If TRUE, text that overlaps previous text in the same layer will not be plotted. check_overlap happens at draw time and in the order of the data. Therefore data should be arranged by the label column before calling geom_label() or geom_text().
