The general shape of the line indicates whether the relationship is linear, quadratic, polynomial, power, inverse etc. It will also help determine whether the relationship remains the same over the whole domain or changes.
The scatter of the observations about a line gives a measure of the variation in the observations about the values that might be expected from the line graph.
a bar graph
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.
A scatter plot
A data table is a list of statistics - a graph is a physical representation of the data.

Line Graph
Graphs are used to investigate the relationships and trends of the data collected. It is easier to see a pattern in a graph than a table of data.
