How to plot just the legends in ggplot2?

Question

I'm currently working with igraph and have colour labelled my vertices. I would like to add a legend Indicating what each colour represents.

What I can think of at this point is to use ggplot2 to print only the legend and hide a bar plot. Is there a way to just output the legend?

I used the ggpubr package - makes it very easy!

# Extract the legend. Returns a gtable
leg <- get_legend(p)

# Convert to a ggplot and print
as_ggplot(leg)
