Is the nebula located on a HR diagram?

Nebulae themselves are not directly plotted on the Hertzsprung-Russell (HR) diagram, which is a graphical representation of stars based on their luminosity and temperature. However, nebulae are often the regions where stars form, and the stars that emerge from these nebulae can be represented on the HR diagram. The HR diagram primarily focuses on the evolutionary stages of individual stars rather than the nebulae from which they originate.
