After years of playing Coriolis, it turned out that memorizing and understanding the current factions of the Third Horizon was a pain for my players. Indeed, the factions are not half as "easy" to figure out than in most games, and I eventually felt that creating a visualization was necessary.
This was an amazing occasion to test Vega's ability to create an appealing radial visualization. I was rather disappointed to figure out that Vega-lite does not work with hierarchical datasets, as they prove to be quite popular and common, and working with "pure" Vega is definitely more cumbersome.
I then extracted that visualization in SVG, and further tweaked it to make it look good. You can find the results below. If you'd like a translation, don't hesitate to ask!
