On top of the page, you see the Voronoi diagram. The horizontal axis represents heat and the vertical axis represents humidity. The visible diagram area represents all mathematically possible values. Note that the further you go from the center, the less likely they will become, with the area close to the border being extremely unlikely (<0.1%). By default, the value range of heat and humidity is from −37.5 to 137.5, with 50 as the midpoint. But most values will be somewhere between 0 and 100 by default.
-Red dots represent the biome points, and they are labelled by default by their (heat, humidity) coordinates. Dark green border lines represent the boundaries of Voronoi cells and the large colored areas represent the biomes themselves.
+Red dots represent the biome points. Dark green border lines represent the boundaries of Voronoi cells and the large colored areas represent the biomes themselves.
By default, a grid is displayed. A grid line is shown for every 10 units (unless the value range of heat or humidity is very large).
