What is the difference between euler and venn diagrams

But no matter how geographically accurate the place names are, Irish commenters predictably objected to being included in anything labeled with the word "British". Another such diagram that includes more islands can be found here. These sweet and sour doodles are true Venn diagrams.

They were produced by Jessica Hagy of Indexed , a blog full of wonderful diagrams and graphs jotted on index cards.

The diagrams clearly show that the lyrics make no sense at all. Nevertheless, the song was number one at the time this was written. Speaking of music, here's a t-shirt for music snobs featuring a two-set Venn diagram.

From the product page:. Nothing is any good if other people like it. We've just proven it mathematically. I have a theory that the only thing cartoonists bothered learning in math class was Venn Diagrams. Ellipses can work for up to five categories, but beyond five, strange shapes need to be used to weave in and out of all the intersection combinations.

Five is already pretty complex to read, but as soon as these strange shapes come into play, reading the diagrams becomes nearly impossible, and text descriptions of the relationships are often easier to understand. This brings us to why so many of these diagrams are funny. The vertebrate and invertebrate Venn diagram we showed you earlier suggests that some animals can simultaneously have a spine and not have a spine.

While this may not be hilarious, anyone who took sixth grade science class can tell you that it is rather silly. Some creative labeling like in the Euler diagram below always helps, too. We know Euler diagrams can be funny, but can they be useful?

Some diagrams embed quantity information using the area of each portion of the diagram. On their own, Euler diagrams like this give you a fairly good general idea of the involved values.

Reading exact quantities out of them would be a bit tough, but for gaining an overview, they are good. This particular graphic uses these Euler diagrams as small multiples, letting you compare regions. They do a good job of showing overlap in categories. They do a reasonable job of showing quantity. You might be able to use an Euler or Venn diagram. Notify me of new posts via email. Share this: Twitter Facebook. Like this: Like Loading Clear analysis and great use of diagrams.
