As an example we developed a well known game in Tableau. We created the 1-1 level of Super Mario Bros in a Scatterplot using a Tableau Extension. Read our blog to learn how we did it.
This was a fun project and proved that extensions are a very powerful Tableau addon. We understand your business does not benefit on developing games in Tableau. This extension merely displays the opportunities Extensions can offer.
If you have an exciting use case to develop a Tableau Extension, please let us know, we would love to get in touch and see if we can develop new functionality in Tableau.
