What is a Tableau Dashboard Extension?

Tableau dashboard extensions are web applications that have two-way communication with the dashboard. Dashboard extensions enable all sorts of scenarios, like letting you integrate Tableau with custom applications, making possible for you to modify the data for a viz, or even creating custom visualizations inside the dashboard. A dashboard extension is just one type of extension that can be built using the Tableau Extensions API.
