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…

  • Is it worth connecting my cities with roads early in Civ 5?
  • Why does Gandhi want to nuke me?
  • Pink number when clearing barbarian encampments?
  • Are Declarations of Friendship worth it?
  • Continue a Civ5 game over internet that started on LAN
  • What is the formula for city connection income?
  • for all of the units, similar to the chart on this site for vanilla and for Gods and Kings.

  • Connection to capitol without port
  • Is there a distance penalty for settling cities?
  • Hostile takeovers: Does your civilization receive the benefits of wonders?
  • What bonuses does a “deity” level AI get and how do I deal with them?
  • AI Civ having another civ's specialty unit
  • After buying the deluxe version of civ5 on Steam, where is the soundtrack?

    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:
