I discovered these graphs from a tweet by Jon Walton:

When researching the quote “Lies, Damned Lies, and statistics” for this post it seems that the origin is slightly uncertain. It is first used by Mark Twain though he attributes it to Disraeli (19th Century British Prime Minister); however there is no known record of Disraeli saying it.

It is important for students to be critical when analysing data; this is particularly true when using software for data analysis  Just because you can make a graph showing the relationship or make a map showing the relationship it does not mean there is a real relationship. It is important to consider the theory behind the claim.
