I made this diagram for the Risk (game) article. I wanted to make all edges rectilinear or at 45° angles but had to use two irregular angles (between Ural and China, and between Middle East and East Africa).
Is there a way to draw the graph with all edges rectilinear or at 45° angles, especially those within a continent (e.g. Ural-China)? Moving the vertex China left one space isn't a solution as Mongolia-China then becomes irregular.
Thanks,

Experiment with rotating everything surrounding Irkutsk clockwise, the see if that lets you move China left one cell. Duomillia ( talk) 00:43, 15 June 2021 (UTC)
Wait, now you are in trouble China to Siberia. Never mind Duomillia ( talk) 00:45, 15 June 2021 (UTC)
Ok. Try this.
Push Siam to where China is, moving Australia to the right. Push China to where Siberia is. Move all of Siberia/Japan/Mongolia up one.

Still stuck for Mongolia this time. Next, rotate Siberia/Japan/Mongolia cc by just a bit, so it forms a square instead of a diamond.

As for Middle East to East Africa, do you permit your routes to cross over each other? I suspect that's the only way to accomplish part 2. Do South Africa > Madagascar > East Africa > Egypt > right

I found a way to make the other connection work:
W.Europe | — | S.Europe | —— | Middle East | |
⟍ | | | Egypt | | | ||
———— | — | N.Africa | —— | E.Africa | |

Also, the above solution for Ural–China forces the Alaska–Kamchatka link to break the alignment. An alternative solution for Ural–China without that problem is: move 6,5,12,4,8,10,2 up one space; move 1 and 3 to the right one space; and move 9 up and to the right one space; then move Australia over (several positions work), and move North America up one space to re-align the Alaska–Kamchatka link. -- 116.86.4.41 ( talk) 08:59, 15 June 2021 (UTC)

A dealer bought a car for#1440000. At what price must he sell it in order to make a profit of 20% on the selling price?
