In this blog post I show how to get started with Tableau to do some simple yet interesting data visualisations. Using a list of all Summer Olympic Games medal winners since 1896, I used Tableau Public to uncover some simple yet interesting facts about the games and about recent history.
What is Data Visualisation?
I like the definition in TechTarget: Data visualisation is a general term that describes any effort to help people understand the significance of data by placing it in a visual context. Patterns, trends and correlations that might go undetected in text-based data can be exposed and recognized easier with data visualisation software.
