I am a beginner at circos plot and have been stuck at a problem from the past week.
I have used the same code for group by regions with some minor changes.
Now, I would like to insert a new track of Histogram/Frequency bar plot after the first track that is South Asia, North America etc.
So after the first track, I want to plot the flow values for each regions as histograms or frequency bar plot.
Any help would be appreciated.
