# Venn Diagram Calculator

## Venn diagram online

The Venn diagram calculator and problem solver allow you to easily solve problems with**two**,

**three**, or

**four**circles.

Enter the number of items for each group or part of the group, and this calculator will calculate the corresponding groups. Alternatively, change the input field to 'Data list'; in this case, enter the list for each group, and the calculator will calculate the intersections and draw the Venn diagram.

## Venn diagram example

In this example each student can learn one or more of the following subjects:

Science, Physical education, and History.

If you press the 'Sample labels' button, and then 'Calculate', the Venn diagram maker will create a Venn diagram with names for every group and intersection.

If you press the 'Sample data' button, and then 'Calculate', the Venn diagram calculator will create a Venn diagram with a list of items for every group and intersection.

If you press the 'Sample total' button, and then click 'Calculate', the Venn diagram calculator will create a Venn diagram based on the quantities of items in the groups and intersections.

## How to use the venn diagram calculator:

The Venn diagram calculator, helps you to solve venn diagram problems.

### 1. Data list:

- Enter the list of objects for each group, and the Venn maker will calculate all the intersections.
- In this case, the "
**Output**" field will appear, and you can choose one of the following options: **Number of data items**: Shows the quantity in each group and intersection.**Data list**: Shows the items in each group and intersection.**Item quantity and data list**: Shows the number of items and the items in each group and intersection.

### 2. Number of data items:

- Enter the number of items in each group and intersection.
- For groups with intersections, you can enter two numbers:
**All**: The number of objects, including the intersections.**Only**: The number of objects exclusively belonging to this specific group.- Each time you enter a number, the Venn diagram calculator will check if it can calculate the number of items in any connected group or intersection based on the numbers you have already entered.
- If possible, it will calculate the number of items and show it in brown.
- The Venn diagram calculator will display the calculation.
- After entering all the numbers, press the "Calculate" button, the Venn diagram maker will to generate the Venn diagram.
- It is possible to generate the diagram even if some of the data is missing. In this case, the diagram will only include partial numbers.
- The diagram will show only the number of items in the smallest groups.
- For example, if 'A∩B' exists but 'A∩B only' doesn't exist, it won't show any number.

### Fields

**Title**- Fill in the chart title and font size**Subtitle**- Fill in the chart subtitle and font size__Input__**Data list****Number of data items**__Output__

Relevant only for the "Data list".**Number of data items****Data list****Item quantity and data list****Group**- Enter name and choose the color. Fill in a space for the empty group name**Intersection**- Enter intersection name. Fill in a space for the empty intersection name**Circles**- Choose the number of circles in the Venn diagram.**Background**- Change the color of the diagram area.**Border width**- The cycle border. Fill zero for no border__Border Color__**Darker**- The same color as the circle, but darker.*Darker level*- Range: 0 to 100.

0 - the border color will be the same as the bar color

100 - the darkest possible color - black.**One color**- Your chosen border color for all the circles.*Border color*- choose the color.**Opacity**- The circles' opacity**Font**- To customize the appearance of your text, choose font type, font size and color**Download chart**- Use the camera icon to download a PNG chart**Circles overlap**- You can control the level of circle overlap by adjusting a slider after generating the diagram.**Text Distance**- This is the text distance from the diagram center. You may increase the distance to improve clarity.**Remove all intersection labels**- When this feature is enabled, it excludes labels of intersections and shows only numbers.**Remove mutually exclusive intersections**- When this feature is enabled, it excludes labels and numbers of intersections that do not overlap.**Remove no group label**- When this feature is enabled, it excludes the 'no group' label .

### What is a Venn diagram?

A Venn diagram is a graphical representation of the relation between groups. Two circles partly overlap if some units will appear in both groups. If any unit appears only in one group, then the circles will not overlap.

### How to solve a Venn diagram problem.

#### When problem contains numbers of items

- Read the question.
- For each number, determine the relevant group or intersection.
- Enter the labels.
- If the number is for the entire group, enter it on the "All" field of the relevant table.
- If the number is for the group but without the intersections, enter it on the "Only" field.
- When you enter a number, the calculator will attempt to calculate the corresponding values and display them in brown

In this scenario, the calculator will generate step-by-step solution in the dedicated solution paragraph. - Press the "Calculate" button, and the venn diagram calculator will generate the ven diagram

#### When problem contains data lists

- Read the question
- Enter the labels.
- Enter comma delimited list of values per each group.
- Choose the output, number, list or both.
- Press the "Calculate" button, and the venn diagram calculator will calculate all the intersection lists generate the ven diagram.
