In this module, you will learn how to use the Word Cloud Power BI Custom Visual.  The Word Cloud is often used for mining large amounts of text data to determine the number of times certain words are used.

Module 20 – Word Cloud

Downloads

• Power BI Custom Visual – Word Cloud
• Dataset – Shakespeare Plays.csv
• Completed Example – Module 20 – Word Cloud.pbix

Key Takeaways

• Great for parsing unstructured data
• Utilize stop words to remove commonly used filler words like a, the, an, etc…
  • You can use the default stop word setting that is provided and/or add your own stop words that you would like the visual to eliminate.
• The size of the words in the visual tell you how frequently the word is used.

This Word Cloud shows the most commonly used words in Shakespeare plays.

• Under the Format paintbrush there are quite a few customizations that can be made to the appearance of the Word Cloud.
• First under the General section of the Word Cloud you will find properties to adjust the position of the visual and the maximum number of words that can be displayed. Here you can also control the font sizes used.

• Under Data colors you have the ability to change which colors are used for the words that are visualized in the Word Cloud.

• The Stop Words property allows you to turn on the Default Stop Words that are built into the visual, or add your own by simply typing each word separated by a space in the Words property.

• Using the Rotate Text settings you can adjust the angle that each word is displayed at. You provide a Min and Max Angle and the words are automatically displayed between that range of angles. You can even set the Max number of orientations which sets how many possible word rotations can be used between the min and max angles set.

• In addition to these properties, you have a set of settings that appear on every visual to adjust the background color, add a border around the visual and lock the aspect ratio.

A picture is worth a thousand word. But if you can present the words themselves as a picture, it’s worth even more.  To make this art easy and fun for everyone, this week, Word Cloud is joining the growing Power BI custom visuals family.

The world of unstructured data is having explosive growth now with text content. you see text everywhere in the social media be in product reviews, comments, messages, announcements or even simply with status updates.

While Traditional charts and visualization techniques are great at making sense of structured data, they generally fall short when it comes to textual data. We often have to look for creative new ways for presenting text data. Word Cloud makes this experience exciting and fun in Power BI.

Word Cloud is a visual representation of word frequency and value. Use it to get instant insight into the most important terms in your data.

With the interactive experience of Word Cloud in Power BI, you no longer have to tediously dig through large volumes of text to find out which terms are prominent or prevalent.  You can simply visualize them as Word Cloud and get the big picture instantly and user Power BI’s interactivity to slice and dice further to uncover the themes behind the text content.

This visual also puts you in control on the appearance of the work cloud, be it the size or usage of space and how to treat the data. You can choose to break the words in the text to look for the frequency word or keep word break off to project a measure as a value of the text. You can also enable stop words to remove the common terms from the word cloud to avoid the clutter. By enabling rotation and playing with the angles allowed, you can become very creative with this visual.

Word Cloud is slick and adds a new dimension to the Power BI custom visuals experience. Check out this video to see this in action.

To use, simply import the Word Cloud from the Visuals gallery to your Power BI report and use it with a text column. Optionally you can also use a measure to provide weightage to the text. If none provided, it will simply use the frequency.  Check out the formatting pane for more options.

As usual, we can’t wait to hear your thoughts and your ideas for improvements.

Enjoy!

Now, go, try it out and have some fun and explore your unstructured text data.

In this article, we’ll look at how to create a Word cloud generator in Power BI Desktop, including importing data, customization and more.

In my last article, Power BI Desktop Interactive chord diagrams, we learned about customized visualizations in Power BI Desktop. These visualizations are free to install and we can use them with our data set and customize charts as per our requirements.

Overview

A Word Cloud is a visualization that draws an image from frequently appearing words in the data set. These words are arranged in a cloud shape. The size of the words in the cloud image is proportional to its frequency.

Below is an example of how Word cluster looks like (Image Courtesy – Wikipedia)

We can use word clusters to display keywords, tags, etc. We can quickly locate the items in the Word Cloud based on the size and color of the word.

For example, in the above example, we can see that the fewer words are appearing in the larger font size that shows the most used keyword as per the conditions defined.

We can use Power BI Desktop to create an interactive visualization with control on the appearance of the word cluster on the text, size, color, number of words, background, rotation etc.

Importing Sample data for Word Cloud Generator

To create a word cloud generator, we’ll first need data. In this example, we will use sample data books.csv from GitHub. This data shows the title, author, genre and publisher details.

Click on Raw, copy and save the data into.CSV file. We will import this.CSV file to create the Word cloud generator in Power BI Desktop.

Now open Power BI Desktop and click on ‘Get Data’. Choose ‘TextCSV’ source from the list.

Provide the location of the source data (books.csv) and click Open.

We can get a preview of the data here. If we do not want to make any changes in the data, then click on Load.

In this example, some of the fields contain blank values as well. Therefore, we do not want those blank values data to create a Word Cloud generator. Click on Edit

In this example, some of the fields contain blank values as well. Therefore, we do not want those blank values data to create our Word cluster. Click on Edit

In this example, some of the fields contain blank values as well. Therefore, we do not want those blank values data to create our Word cloud generator. Now click on Edit to make changes in the data.

This opens Power Query Editor. Click on the columns and uncheck the blank value option from the publisher column.

Similarly, uncheck the blank value from the ‘Author’ column.

Once we are done, click on ‘Close and Apply’

Now, we can see the fields in our dataset in the ‘Fields’ section.

Importing from Microsoft AppSource for Word Cloud Generator

We can get the Word cluster from the Microsoft AppSource. We can view a brief description and tutorial video clip on the page.

Click on ‘Get IT Now’ and click on continue to accept the terms and conditions. Please note you need to log in with a work account in order to install a Word cluster in Power BI Desktop.

Click on Download for Power BI

Save the .pbiviz file into the desired location. We will use this file to import into Power BI Desktop.

Now in the Power BI Desktop, Click on custom visual section From File. We get a warning message that the custom visuals are not provided by Microsoft and we should consider security or compliance risks before proceeding.

Click on Import to move further.

Provide the path of the Power Bi visual file (.pbiwiz) downloaded earlier and click open.

This imports the custom Word cluster visual and results in the following success message.

We can see below the icon for Word cluster in the visualization section of Power BI Desktop now.

Custom visualizations

Before we create the Word cloud generator, let us understand the sample data further. Put a check on the Author and Publisher columns and we can see both columns data on the left-hand side.

Let us increase the font size of the data to view it properly. To do so, increase the font size from

Format > Column header > Text Size

Format > Values >Text Size

Data is now visible properly. Click on publisher column and select Count.

This shows the count of the publisher for the authors.

We can sort the data here easily. Simply, click on the column name and sort it in ascending or descending order.

Now, our data looks like below and we are now ready to create a Word Cloud generator from this.

Click on Word Cloud Generator icon from the Visualization section and this draws a blank chart.

Drag the fields from the data set in the category and values section. Below we can see fields as

Category -> Authors

Values -> Publishers

This draws up the Word cluster based on the data we selected.

If we click on any particular word, it shows up the details of that particular author. However, as we can see, for author John , it just looked at the first name John and combined the data together.

Similarly, we can change the value to Count of the publisher from the drop-down option.

By default, the Word cluster looks for the first word in the value section in Word Cloud Generator. It does not look the entire word as a single word. If we want to create a Word cloud generator for the complete name, go to General ->Word-breaking. By default, it is turned on. Move the slider and turn off the word breaking.

We can now observe the Word cluster; this is now showing the complete name of the author. If we look at our data table, Steinbeck John is having the highest count and it reflects in the Word cluster. The font size of Steinbeck John is largest in the visual.

Now if we click on it, we can see that only one row for it.

Stop Words in Word Cloud Generator

We normally use some common words, for example, a, an, the, etc. Sometimes we do not want these words to appear in the Word cluster since they are commonly used words and if our dataset contains these words, it would be difficult to get a true picture of Word cluster by showing frequently used words.

In the below example, we created a Word Cluster visual for ‘Title’.

We can see above, there are a few words (the, of) appearing in the visual and we do not want to show them in this Word cluster.

To exclude those words, go to format -: Stop Words.

Move the slider to turn on this feature and enable Default-Stop Words.

Default stop words removed commonly used stop words from the Word Cloud Generator.

We can see the below visual after we turned on Default-Stop Words.

We can also specify words to exclude apart from the default stop words. For example, we want to exclude the word ‘Vol’ so specify ‘Vol’ in the words section as shown below

If we want to exclude multiple words, specify them with space. For example, in below visual, we excluded ‘Vol data’ keywords.

Customization in Word Cloud Generator

• Rotation: we can specify the min and max angle of rotation along with Max number of rotations.

  Go to the format section and Rotate Test. Change the desired property and observe the change in the Word cluster visual

  

  

• Title: We can set the title of the Word cluster visual from the format ->Title section. If we do not want the title, turn it off.

  

  Specify the title, font colour, size, alignment and we can see that in the Word cluster visual

  

• Background: we can change the background color of the Word cluster visual using this property. Go to Background in the format section

  

  Turn it on and select the background color and transparency level

  

Conclusion

Word Cloud Generator in Power BI offers an interactive method to do the analysis for frequently used words, text with customization. In this article, we reviewed how to create a Word cloud generator with Power BI Desktop. Explore these techniques with your own data sets and enjoy clouding!
