Is there a chart showing all unit upgrade paths in Civilization 5 Brave New World?

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 and for Gods and Kings.


I made a basic version which is generated directly from the game files, and includes all unique units:

Notes:

  • Each column represents one era.
  • Dotted lines represent upgrades by ruins.
  • Grey lines represent special UU upgrade paths.
  • The unit "combat type", listed under the unit name, controls which promotions are available to it.
  • Missiles and non-combat units cannot be upgraded and are omitted from the chart for brevity.

I made my own chart for this: Unit upgrade picture
