Which diagram relates star luminosity to temperature?

The Hertzsprung-Russell Diagram is a crucial tool in the field of astrophysics that illustrates the relationship between the luminosity (brightness) of stars and their surface temperature. On this diagram, stars are typically plotted with temperature on the horizontal axis and luminosity on the vertical axis.

The most significant aspect of this relationship is that hotter stars, which are represented on the left side of the diagram, tend to be more luminous compared to cooler stars on the right. This pattern allows astronomers to classify stars based on these two important characteristics, facilitating our understanding of stellar evolution and the life cycles of stars.

While other diagrams listed may serve different purposes, such as classifying types of stars or representing their positions in the sky, they do not specifically illustrate the direct correlation between star luminosity and temperature in the same comprehensive manner as the Hertzsprung-Russell Diagram does.
