An H-R Diagram (Hertzsprung and Russell) is used to classify stars based on their size and brightness. The main sequence stars, such as our sun, are the medium stars, and take up the middle f the diagram, while the giants and dwarves are located on either side. http://www.eso.org/public/outreach/eduoff/cas/cas2002/cas-projects/bulgaria_comaber_1/hr_local.gif <- shows what an H-R diagram looks like.

hr. NOT ho
To read an HR diagram, look at the stars' luminosity on the vertical axis and their temperature on the horizontal axis. The main sequence represents stars in stable fusion. Interpret data by noting a star's position on the diagram to determine its temperature, size, and stage of evolution.
Of course they are on the HR diagram. They are simply not on the main sequence.
The HR diagram contains only stars - so everywhere.

The red dwarves.
Up at the top right. If you look on the Australian Telescope National facility website, their HR diagram shows this clearly.
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.
its located somewhere
All stars.
Slightly to the right of centre on the main sequence. If you look on the Australian Telescope National facility website, their HR diagram shows the position of the sun.
The HR Diagram depicts the relationship between a star's luminosity (brightness) and temperature. Stars appear in different colors on the diagram, ranging from hot blue stars to cool red stars. The main sequence runs from hot, blue stars in the upper left to cool, red stars in the lower right.
