Line of best fit
A scatter graph.
showing data and seeing if it's closely related or not related at all
No. There is no symbol showing between the y and the 0.
There is quite a high degree of linear agreement between the two variables with one showing an increase when the other shows a decrease.
The difference between graphs and charts is mainly in the way the data is compiled and the way it is represented. Graphs are usually focused on raw data and showing the trends and changes in that data over time.
A scatter diagram. A line diagram will not be as good at showing a relationship that is non-linear (not a straight line).

A scatter plot.
scatter graph of stars showing the relationship between the stars' absolute magnitudes orluminosities versus their spectral types orclassifications and effective temperatures.
It is a chart showing a scatter chart of stars according to their temperature and their luminosity (or absolute magnitude).

Line graph. I would suggest a scatter graph. That would allow you to determine the line of best fit.
The Hertzsprung-Russell diagram is a scatter graph of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their spectral types or classifications and effective temperatures.
Ejnar Hertzsprung and Henry Norris Russell,working independently, realized the relationship between a star's temperature and its brightness.Together, in 1910, they formed what is now known as the Hertzsprung--Russell diagram or HR Diagram.It's a scatter graph showing the relationship between a star's absolute magnitudes, their spectral types and temperatures.

The Hertzsprung--Russell diagram (or H-R diagram) is a scatter graph of stars showing the relationship between the stars' absolute magnitudes or luminosity versus their spectral types or classifications and effective temperatures. See related link for a pictorial
