Multivariate is probably the most accurate answers. Graphs need not be bivariate - you can have graphs in 3 or more dimensions - not easy to visualise in more than 3-d but that does not mean they cannot exist. Graphs need not represent exact relationships - as any scattergram will demonstrate. Graphs are simply visual representations of information, presented in a form that [hopefully] conveys he information in an effective way. For one of my favourite semi-numeric graphs follow the link to see a graphical representation of Napoleon's invasion of Rusia.
Graphing actually show you trends and gives you information you may not "see" otherwise.
Graphs help you see relationships in things such as inflation in money, or rising population.
There are various types of graphs. You need to be more specific. Graphs exist for thousands of subjects, and each one is different. But, basically, you need to gather all verifiable information on the subject in question before you begin.
Yes, without exception.
so when you need to find out information you wont get the wrong answers

All we need here is a graph to interpret
To limit the need for long handwritten notes. It makes the information clearer and neater.

There are a couple options. You can create graphs, such as bar graphs, line graphs, x-y plots, and pie charts at https://nces.ed.gov/nceskids/createagraph/default.aspx. The program is directed at children but I have used it to create very professional graphs. If you are looking for more customization, try using Microsoft Excel. You can find great information on this tactic by Google-ing it.
