Circular plot code

[royarkaprava]

Hi Yan, Great website. I was trying to use your code to create a circular plot as in "https://www.r-graph-gallery.com/311-add-labels-to-hierarchical-edge-bundling.html". But your code is ending with the warning "Removed 1 rows containing missing values (geom_edge_path)." without creating the plot. I am not sure where the problem is. Can you please help?

Best, Arkaprava
