It may not technically be a Venn Diagram but I still think it is a legitimate way to represent something - and do it better than the author's alternatives.
You have to look at the chart differently but I don't think this makes it a bad graphic.
Each intersection is a way of representing what the two intersecting groups have in common, rather than demonstrating what the groups are.
The question is, "What do doctors and TSA agents have in common?" and the answer goes in the intersecting region.
While not technically a Venn Diagram I think it is still a useful graphic.
- kleiba 16y agoI think you're right, the whole "problem" he's addressing stems from the fact that someone called the original graphics a Venn diagram when they shouldn't have. However, I do think that one of his alternatives is actually quite good, and does convey the same information as the original diagram: http://eblong.com/zarf/pic/thod/venn-inside.png http://eblong.com/zarf/pic/thod/venn-inside.png
- Retric 16y agoI disagree. "Venn diagrams or set diagrams are diagrams that show all hypothetically possible logical relations between a finite collection of sets" http://en.wikipedia.org/wiki/Venn_diagram http://en.wikipedia.org/wiki/Venn_diagram There is nothing wrong with showing Venn diagrams of property's of something. It's really just another set. PS: Numbers are abstract ideas not physical objects. So, Venn diagrams where really designed to show relationships between ideas.
