Since we were able to enrich the content found at input URLs with valuable information, the natural next step is to start visualizing our data. Although the different techniques of Exploratory Data Analysis have been thoroughly discussed within Chapter 4, Exploratory Data Analysis, we believe it is worth wrapping up what we have covered so far using a simple dashboard in Kibana. From around 50,000 articles, we were able to fetch and analyze on January 10-11, we filter any record mentioning David Bowie as a NLP entity and containing the word death. Because all our text content is properly indexed in Elasticsearch, we can pull 209 matching articles with their content in just a few seconds.

We can quickly get the top ten persons mentioned alongside David Bowie, including his stage name Ziggy Stardust, his son Duncan Jones, his former producer Tony Visconti, or the British prime minister David Cameron. Thanks to the GeoLookup service we built, we display all the different places mentioned, discovering a clique around the Vatican City state where the cardinal Gianfranco Ravasi, head of the pontifical council of culture, tweeted about David Bowie's famous lyrics of Space Oddity.
