The type of graph best to use to show the relationship between sets of data depends on the nature of the data and the purpose of the comparison. For comparing individual data points, a scatter plot is often used. For showing trends or changes over time, a line graph is typically more suitable. Bar graphs are useful for comparing different categories of data. It is essential to consider the specific characteristics of the data and the message you want to convey when choosing the appropriate type of graph.

A scatter plot would be best for non-related data points. A line graph would be best for related data points.
The answer depends on what sort of variables the data are (qualitative, quantitative-discrete, quantitative-continuous are; the nature of the relationship (if any) between the data sets; how much information you wish the graph to convey and how much you would prefer to describe in the accompanying text.
The second one.

A double bar graph is a graph that uses pairs of bars to compare and show the relationship between data. However, a double line graph is a grid graph that uses pairs of lines to compare and show the relationship between data.
Any kind of properly drawn graph does. That's what graphs do.

If your data doesn't graph into a straight line, it may suggest a nonlinear relationship between the variables. In such cases, you can try fitting a curve or using a different type of regression analysis, such as polynomial regression or exponential regression, to better capture the underlying relationship in your data. It's important to choose the appropriate model that best fits your data and the underlying theory.
Bar graph
A line graph is the best choice for graphing your data when you're showing quantitative data (numbers) over time. A bar graph is best when you're showing qualitative data and quantitative data at the same time. A line graph could be: Laps run in a minute. A bar graph could be: Laps run by Legolas, Gimli, Hermione, and Harry in 5 minutes.
