Summary

[edit]
Description
English: Four color theorem. Second of three diagrams. Step 2: Place a point or dot or node in each contiguous province in Germany. Put the points anywhere you wish. If two provinces share a common border, then draw a line between the two points. No common boundary? Then don't draw a line. Pick up the color of the province inside the circles.

Note: I created this chart originally for use in the Citizendium article "Four color theorem". The earlier diagram was also public domain. In the diagrams it is noted "PD" (public domain) here.
