In the H-R diagram, the brightest stars are located in which region?

Explanation:
In the H-R diagram, brightness (luminosity) is shown on the vertical axis, with more luminous stars higher up. So the brightest stars sit near the top of the diagram. The left-right axis reflects temperature (hotter to the left, cooler to the right), not how bright a star is. While some hot stars can be bright, the overall brightest stars—those with the greatest luminosity—are found at the top, regardless of their color. The bottom region contains the dimmer stars.
