#### Solution

## Venn diagram online

The interactive 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. To leave the group name or intersection label empty, simply fill in a space. To add a new line to the label, press Enter after first line and continue to the second line. When you enter a value, the Venn diagram calculator will update the value automatically.

### 1. Data list:

- Enter the list of objects for each set, and the venn diagram calculator 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:
**A**: The number of objects, including the intersections.**A-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 blue.
- After calculation was done you can not change the data.
- The Venn diagram calculator will display the calculation steps in the "solution" section.
- THe calculate will try to calculate on when one value is missing

### 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 intersections' 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 .

### 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 blue

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.
