Surface temperature and Absolute magnitude
main-sequence stars
I'm unable to create visual diagrams directly. However, I can describe how you might illustrate a concept. Start by identifying the main components of the process you want to diagram. Use shapes like circles or rectangles to represent these components, and arrows to show the flow or relationship between them. Label each part clearly for easy understanding. If you need help with a specific concept, let me know!
In a circuit diagram, long straight lines represent electrical conductors, typically wires, that connect various components of the circuit. These lines indicate the path through which electric current flows between components such as resistors, capacitors, and power sources. The simplicity of the lines helps in visualizing the connections and layout of the circuit without cluttering the diagram.

To accurately describe the structure labeled "X" in the diagram, I would need more context or details about the diagram itself. Generally, structures in diagrams can represent biological, chemical, or mechanical components, among other things. Please provide additional information or specify what type of diagram it is for a more tailored response.
Of course they are on the HR diagram. They are simply not on the main sequence.

On the main sequence.
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 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 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.
The HR diagram contains only stars - so everywhere.
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 lower right part of the main sequence in the Hertzsprung-Russell diagram contains the stars that took the longest to reach the main sequence. These stars are low mass and cool, so they undergo a longer contraction phase before they start fusing hydrogen in their cores and settle onto the main sequence.
