There is an unprecedented need for unstructured data analysis due to the massive growth of textual content from sources like social media, product reviews, messages, announcements etc. While traditional charts and other visualization techniques are great at making sense of structured data, they generally don’t work well with representing unstructured data. 

Word Clouds are an excellent way to visually interpret unstructured data and quickly gain insights into the most prominent words in such data, by visualizing word frequency and value.

In this example, a Word Cloud is created for components in Jira. 

To create a Word Cloud:

• Select the ‘Component(s)’ column and right-click > select View> change> Word Cloud.

Refer here to learn more about how to create a visualization.

The following figure shows the resulting Word Cloud.

Configure Word Cloud

• Select your Word Cloud and open the Visualizations Panel.  

The following configuration options are available for Word Cloud:

1. Data Configuration : It lets you choose columns for the following settings:
       a. Column 
             i. Conditional Formatting
       b. Size By
2. Visual Configuration : It lets you configure the visual appearances and interactions of the Word Cloud. 
        a. Container Settings
        b. Visual Interactions 
3. Visualization Level Filters : They let you filter the data in the specific visualization without impacting the data in other visualizations.        
   Refer here to learn more about Visualization Level Filters.
4. User-Defined Colors : They let you add meaning to a data point by associating a specific color to it. User-defined colors also help you to differentiate a data point from the rest.

Data Configuration

• Click on the  icon for data configuration options.

Column

You can specify the column whose values should appear as ‘words’ in the Word Cloud.

To change the column:

1. Click on the icon to remove the existing column. 
2. Drag the desired column from the Data Panel and drop it on the Visualizations Panel’s “Column” section.

Note: You can also type the column name in the Data Panel to quickly find it.

Note that Word Cloud considers the value in each row of the column as one word. When dealing with textual data containing sentences (e.g. Issue summary), Word Cloud doesn’t make much sense. The following figure shows a Word Cloud for the summary column.

You can break these sentences into words by using the Tokenize formula and then use them in a Word Cloud for better insights into unstructured data. 

'TOKENIZE' formula

Tokenize takes a sentence as input and splits it on a separator (e.g. blank space, comma etc.) and generates a collection of words in a new column. Now you can use the new computed column to generate a Word Cloud. In the following example, a computed column ‘Tokens’ is created. 

There are more formulas available to process Unstructured Data. To learn more about such formulas and Klera’s formula engine, click here.

Drag and drop this computed column from the Data Panel to the ‘Column’ section.

Conditional Formatting

This allows you to show an image with the words, by applying certain conditions. Multiple conditions can be combined as well.

To apply conditional formatting:

1. Click on the   icon next to the column name and select ‘Conditional Formatting’.
2. Define the conditional formatting rule:
       a. Select the criteria from the drop-down.
       b. Provide the threshold value. 
3. Set the format style to choose an image to be shown when the above criterion is true. You can provide the image in the following ways:
   
   • Select Library and click on Search Image to select an image pre-bundled with Klera.
     
   • Select File and click on Upload File to choose one from your machine.
     
   • Select URL and Type In the URL of your image.
     
4. Click on  ‘Add’. 
5. Click on ‘Back’ to return to the Data Configuration. This  icon indicates that the conditional formatting is applied to the column. 

To update the condition for a column:

1. Click on the conditional formatting  icon. 
2. Change the criterion or format style.
3. Click ‘UPDATE’. 

To remove Conditional Formatting:

1. Click on the  icon for the desired column. You will see the criteria listed at the bottom. 
2. Click on the   icon to remove the condition.

To learn more about conditional formatting, refer to the following GIF. 

Note: Steps for conditional formatting are the same for Grid and Word Cloud.

 

Size By

The size of the words represents a certain measured value for each of the words. You can specify the column whose values should be aggregated to represent the size of the words. 

To change the column for word size:

1. Click on the  icon to remove the existing column. 
2. Drag the desired column from the Data Panel and drop it on the  “Size By” section.
3. Click on the   icon to select the aggregate function.

• Aggregate functions for textual data: Count, Unique Count

• Aggregate functions for numerical data: Count, Unique Count, Sum, Min, Max, Avg

In this example, word size is calculated based on the sum of time spent on the issues.

Visual  Configuration

• Click on the  icon for visual configuration settings.

Container Settings

1. To show/hide the header and border, click the toggle switch.  
2. Turn on the toggle switch to show the border for the container. Change the border color, style and width as shown below: 

The following figure displays the effect of various settings for Word Cloud.

Visual Interactions

• Select the target behavior and scope for the coordinated visualization from the below settings. 

To learn more, refer to section- ‘Configure Coordinated Visualization’.

User-Defined Colors

• Click on the  icon for the following color settings. 

Colors of Individual Data Item

It lets you add meaning to a data item by associating a specific color to it and differentiate some data items from the rest. 

For example, the red and green colors may be used to represent “Off Track” and “On Track” issues, respectively. Whereas, orange color may be used for the “Bugs” type of issues to draw attention.

To change the colors:

1. Click on the  icon next to the data item for which you want to change the color.
2. Select the color from the available color grid or click ‘More Colors’.  
3. To restore default settings, click ‘Reset to Default’. 

Configuration Options in Full-Screen Mode

Visualization can be seen in full-screen mode by clicking on  icon. 

Note: Visualizations Panel is not accessible in full-screen mode.

1. Click on   icon at the top-right corner of the container. 
2. Select ‘Configure View’ from the overflow menu. 
   
3. A pop-up form with all the relevant configuration options will appear on the screen.
4. Configure your visualization and click ‘APPLY’.
