A popular way of visualizing text data is using WordClouds. Using Python's WordCloud library this can be done with a column of text data and a few lines of code. 

# SQL output is imported as a pandas dataframe variable called "df"
import matplotlib.pyplot as plt
from wordcloud import WordCloud, STOPWORDS

stopwords = ["my","to","at","for"] # removes any words you may want to exclude from your wordcloud


img = WordCloud(width = 600, height = 400,
                          background_color='black', colormap = 'Oranges',
                          stopwords=stopwords,
                          max_words=200,
                          max_font_size=100,
                          random_state=42
                         ).generate(str(df["TEXT"]))

plt.figure(figsize=(30,20))
plt.subplots_adjust(left=0, right=1, top=1, bottom=0)
plt.imshow(img)
plt.axis('off')
periscope.output(plt)

Here is our result!

  This is great!  Can you provide a bit more insight into the implementation?

  Where is this work done?  Obviously not in-widget or using Blox..

  Hi Sam Nicholls, this is done in the Sisense for Cloud Data Teams product. It sounds like you are in Sisense for BI and Analytics.
