The line of a graph is quite often used to indicate the average of various data points that fall both above and below the line. Very jagged lines get smoothed out, but the trend is the same.

A non-linear graph.
a straight line
1. PICTORIAL GRAPHS. These are the kind found in mathematics and physics textbooks. Their purpose is to simply and clearly illustrate a mathematical relation. No attempt is made to show data points or errors on such a graph.2. DISPLAY GRAPHS. These present the data from an experiment. They are found in laboratory reports, research journals, and sometimes in textbooks. They show the data points as well as a smooth line representing the mathematical relation.3. COMPUTATIONAL GRAPHS. These are drawn for the purpose of extracting a numerical result from the data. An example is the calculation of the slope of a straight line graph, or its intercepts.

In an experiment, the observations always have some kind of random error. It could also be that the relationship between the variables is such that it can't be represented by a smooth line.If the data points do form a perfectly smooth line, you have probably 'cooked' the results, and it will be obvious that you haven't performed the experiment!
A scatter plot would be best for non-related data points. A line graph would be best for related data points.
To get data from a graph efficiently, you can use the gridlines and labels on the axes to determine the values of the data points. You can also use a ruler or a straight edge to help you accurately read the data points from the graph.

It depends on what you are trying to do.
either a scatter graph or a line graph xx :)
Any kind of properly drawn graph does. That's what graphs do.
A line graph is used to display data over time with points connected by lines. This type of graph highlights trends and patterns in the data.
