The largest stars would also be the brightest and that would put them near the top of the Hertzprung Russell diagram.
The Sky Catalogue 2000.0 lists 50,071 stars of brightness down to magnitude 8.0. The brightest star is Rho Cassiopeiae with an absolute magnitude of -9.5, which is about 400,000 times more luminous than the Sun, and its spectrum is G2 like the Sun.
Of course they are on the HR diagram. They are simply not on the main sequence.

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.
They are very hot stars.
The temperature and luminosity of stars.
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.
