Concept 2: Spread of one topic

How to visualize the spread of one topic across the world and its reaction?

When a topic is trendy, often people start to be more interested in it than before. This phenomenon is dependent on the importance of the topic, its nature and the consequences that it can produce.

We would like to investigate how big news may affect the interest in a topic around the world. The user would see the relation between the general interest in the topic (Google Trends) and the discussion around the topic (Twitter). As well, there will be the possibility to see how people reacted to a topic (positively or negatively), what were the words associated to the event and finally how other countries reacted to it.
An example would be the “Brexit”: how people started to get interested in EU only after Brexit had happened. The most popular search term in Google after Brexit was “What is the EU”.


  • Possibility to choose the time line
  • Knowing the reactions about one topic
  • Compare different topics
  • Simple and intuitive


  • Only some topics
  • Sentimental analysis difficult to do
