The HR Diagram compares the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
The Hertzsprung-Russell diagram was created - as the name suggests - by Ejnar Hertzsprung and Henry Norris Russell in 1910

Ejnar Hertzsprung and Henry Russell H for Hertzsprung and R for Russell
The diagram was created by Ejnar Hertzsprung and Henry Norris Russell aound 1910.
The sun is considered a main sequence star on the Hertzsprung-Russell diagram.
The answer to this question is Hertzsprung-Russell diagram
This plot is commonly referred to as a Hertzsprung-Russell (H-R) diagram, named after the astronomers Ejnar Hertzsprung and Henry Norris Russell who independently developed it in the early 20th century.
The two characteristics of a star plotted on the Hertzsprung-Russell diagram are luminosity (brightness) on the y-axis and temperature or spectral type on the x-axis. This diagram helps astronomers classify stars according to their different stages of evolution.
Enjar Hertzsprung lived in 1873-1967 and Henry Russell lived in 1877-1957. They were scientists who worked separtely. They found the same answer about the temperature and color of stars. The diagram that they made is called the Hertzsprung-Russell diargram. It shows the connection between surface temperature and color.The discoverers of the famous Hertzsprung-Russel diagram (HR diagram), which turned out to be an important tool for the analysis of stars.
Brightness and Temperature are the two characteristics plotted on the H-R diagram a diagram used to plot the absolute magnitude of stars and their temperatures
Only if you are very, very careful.
Cool and luminous stars would be located in the top right corner of a Hertzsprung-Russell diagram, in the region known as the red giant branch.
