Is there a chart showing the upgrade paths for the units? Something like
Warrior → Spearman → Pikeman...
for all of the units, similar to the chart on this site for vanilla.
Although not as pretty as the chart on the other question, I made a basic version which is generated directly from the game files, and includes all unique units:

In addition, there's a similar graph posted over at civfanatics. It's (much) prettier and lists strategic resources needed for each unit, though it does not list UUs.
