You can compare two different data sets on the same chart.
The advantage is that you can compare multiple data sets in the same chart
By using multiple lines you can show multiple pieces of data; e.g. if you have a test for the heat of liquids, then you can show multiple different liquids on the same graph. Like water and oil, you can show the water as one line and the oil as another. Saving you the need to make more graphs and making data easier to compare.
A bar graph is useful for showing the amount of the items yours comparing. This is great for a survey too.
Tables use lines and numbers instead of using bars words and numbers..... :) Also, you can't put your beer down on a bar graph :-)
The graph that displays data using line segments is a line graph.

Look at the diagram of my pointing finger: there!

To connect 12 points with 5 lines, you can create a configuration where lines intersect and connect multiple points simultaneously. For instance, using a star-like pattern or a network graph where lines overlap can achieve this. Each line can connect multiple points, allowing you to cover all 12 points efficiently. However, achieving this while ensuring all points are connected might require creative placement of lines.
the brake or cut
A picture graph, instead of using bars or lines to measure quantities, uses pictures. http://www.schools.ash.org.au/revesby/images/pg.gif here's an example
A line graph can have just one line, or several lines (often using differing colours for clarity). Using several lines make it easier to compare changes that have happened over a period of time.
It's easier to use than a single step.
