I already browsed some web dataviz examples but the following libraries does not seem to answer to my dataviz need: polar chart, windrose, circlize, floating.pie, sunburst, plotly. It is quite difficult to explain it by words, I added a picture to illustrate what i look for and wonders if there is a way to automate it with R (or any other?)
I have 4 columns: region,period, product, value. I would like to represent this way below.
