It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).
On the HR diagram the Sun's spectrum is of type G2 which makes it yellow.
The HR diagram compares the luminosity (brightness) of stars against their surface temperature or spectral type. This plot helps astronomers classify stars based on their intrinsic characteristics and evolutionary stages.
The Hertzsprung-Russell (HR) diagram is based on plotting a star's luminosity against its temperature or spectral type. This diagram helps astronomers classify stars based on their evolutionary stage and enables them to study relationships between a star's properties such as temperature, luminosity, and size.
The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
The location on the Hertzsprung-Russell (HR) diagram where most stars lie is known as the main sequence. The HR diagram is a plot of stellar luminosity against surface temperature. The main sequence is a prominent band that extends diagonally across the HR diagram from high temperature and high luminosity to low temperature and low luminosity. The majority of stars, approximately 90% of all stars, are situated along the main sequence on the HR diagram. These stars are often referred to as main-sequence stars. They exhibit a smooth relationship between surface temperature and luminosity, with varying sizes and masses but sharing this common characteristic of lying on the diagonal band from the upper left to the lower right of the HR diagram.

The Hertzsprung-Russel diagram shows brightness versus color (the color reflects the star's temperature).
The HR diagram, also known as the Hertzsprung-Russell diagram, depicts the relationship between the luminosity and temperature of stars. It shows how stars are distributed in terms of their brightness and temperature, allowing astronomers to classify stars based on these characteristics.
Its called an HR diagram or a Hertzsprung-Russell diagram.
Yes, an HR diagram plots a star's luminosity (brightness) against its surface temperature, also known as color or spectral type. This graph shows the relationship between these two characteristics for different stars, allowing astronomers to classify and study them.
On the HR diagram the Sun's spectrum is of type G2 which makes it yellow.

The main reason that the HR Diagram is so useful and important to scientists is, you can tell the size of the star by plotting it on the HR Diagram. The different sizes of stars form a pattern on the HR diagram.
The colors of the HR Diagram are:BlueBlue-WhiteYellowOrangeRed-OrangeRed
The curve that currently contains most stars on the HR diagram is called the "main sequence". It consists of those stars that fuse hydrogen-1, converting it into helium-4.
