Detailed explanation-1: -The Hertzsprung-Russell diagram shows the relationship between a star’s temperature and its luminosity. It is also often called the H-R diagram or colour-magnitude diagram. It is a very useful graph because it can be used to chart the life cycle of a star. We can use it to study groups of stars in clusters or galaxies.
Detailed explanation-2: -The Hertzsprung–Russell diagram, abbreviated as H–R diagram, HR diagram or HRD, is a scatter plot of stars showing the relationship between the stars’ absolute magnitudes or luminosities versus their stellar classifications or effective temperatures.
Detailed explanation-3: -The existence of a Main Sequence in an H-R Diagram indicates that for most stars, there is a correlation between luminosity and temperature. Recall that the x-axis on the H-R Diagram is Temperature and that it’s plotted backwards, and that the y-axis on the H-R Diagram is Luminosity, plotted the right way.
