I tried to plot the same plot as shown in the picture using R. It displayed the results of thematic analysis (qualitative analysis), which tell the readers of open-end answers' themes. I googled it using the key words "circular sankey diagram" but the searched pictures were a little different from what i want. The origin nodes should be centered. I'd appreciate any suggestion.
Since I am not sure the exact name of this kind of diagrams, I have searched any possible answers via goolge and this forum but in vain.
