Use the series of Venn diagram templates on Cacoo as a jumping-off point. Now that you know all about how to make a Venn diagram and include the official terminology and symbology, you should understand how to correctly read one. No matter how many options are added, you know where similarities or preferences lie for them, and the differences between what elements end up sitting inside and outside of the chart.
A set is a group or collection of things, also known as elements. Those elements could really be anything. From the example above, the set is the choices the unnamed group make for their drink preferences. In set theory, we would write this out instead as an equation, listing all of the elements within curly brackets:.
Since the question of the example is which drink their preference is, these people end up divided into groups by their choices:. Because we are offering five different drink options, we end up with five individual sets, which are then represented within the Venn diagram.
As you explore more set relationships, visualizing your work with Venn diagrams is a powerful and easy way to communicate these relationships with ease. Our library of shapes can help you easily create diagrams from scratch or you can start from one of our hundreds of pre-made templates to simply plug in your info and go. The overlap, or intersection, of the three sets contains only dog. Of course, Venn diagrams can get a lot more involved than that, as they are used extensively in various fields.

The Venn diagram we know today was developed by the English mathematician John Venn. Since then, the Venn diagram has been the center of extensive research from many other notable scientists, among them A. They have become an essential visualization for mathematical study, whether the traditional 3-circle diagram or more intricate versions including spheres and ellipses, for areas such as set theory, logic theory, rotational symmetry and the study of complex shapes and numbers such the tesseract.
For such a straightforward diagram, the Venn has been mislabelled over the years. Venn diagrams are essentially a more specific type of Euler diagrams. Here is a handy Euler diagram visually describing that all Venn diagrams are Euler diagrams, but not all Euler diagrams are Venn diagrams:.
The golden rule of the Venn is that it always visualizes all possibilities, even if none of the data fits into these intersections, whereas an Euler diagram visualizes only the categories there is data for. If we were to force the diagram above to fit the parameters of a Venn diagram, we would have to imagine that some Venn diagrams exist that are not Euler diagrams.
To put this into context, this is like stating that some animals are not penguins and therefore some penguins are not animals. If the orange data set represents Jans, the pink data set represents Anwar, and the blue data set represents Lucy, we can organize this information in two different ways.
The Euler diagram shows just the possibilities we have factual data for already. Venn diagrams are, at a basic level, simple pictorial representations of the relationship that exists between two sets of things. However, they can be much more complex. Still, the streamlined purpose of the Venn diagram to illustrate concepts and groups has led to their popularized use in many fields, including statistics , linguistics, logic, education, computer science, and business.
A Venn diagram could be drawn to illustrate fruits that come in red or orange colors. Below, we can see that there are orange fruits circle B such as persimmons and tangerines while apples and cherries circle A come in red colors.
Peppers and tomatoes come in both red and orange colors, as represented by the overlapping area of the two circles. You might also draw a Venn diagram to help decide which of two cars to purchase.
The Venn diagram shows the features that are exclusive to each car and the features that both cars have. Below, we see that Car A is a sedan that's powered by gasoline and gets 20 miles per gallon, while Car B is a hybrid, gets 40 miles-per-gallon for mileage, and is a hatchback. The shaded region where the two circles overlap shows the features that both cars have in common, which include a radio, four doors, Bluetooth capability, and airbags.
The Venn diagram graphically conveys the similarities and differences between the two cars to help decide which to purchase. A Venn diagram in math is used in logic theory and set theory to show various sets or data and their relationship with each other.
A Venn diagram is read by observing all of the circles that make up the entire diagram. Each circle is its own item or data set. The portions of the circles that overlap indicate the areas that are in common amongst the different items whereas the parts that do not overlap indicate unique traits among the item or data set represented by the circle. They are called Venn diagrams because the diagram was developed by John Venn, an English logician. The middle of a Venn diagram where two or more sets overlap is known as the intersection.
