A scripted UI mod that recreates the alignment triangle from Hearts of Iron 3. To access the graph just click the diplomacy button and navigate to the country list menu. On the top right of you'll see the alignment graph button.
The Triangle assigns you based on what your ruling ideology is and how popular it happens to currently be. Top of the graph is Democracy, left is Communism, right is Fascism and center is Non-aligned.
Hovering over any of the flags will list the nation's ruling party, political ideology and party popularity.
This mod only works with mods that retain those 4 ideologies. I will make patches for other mods that add more ideologies like FR, KR and TNO.
Sadly it seems GUI mods like this change the HOI4 checksum and therefore are not Ironman compatible.
