You can create a table of contents and then use that as a data source and actionable link on a Tableau Dashboard. In the example below, I started with an excel file which contained the Name, Author, and URL for various visuals already on the web. I then connected to this excel file in Tableau, and created a dashboard where the action target is the URL of the visual.
Just for fun, I set all of the links to use the PNG picture output of the original visual. You can always create a dynamically generated PNG image from any Tableau visual simply be adding ".png" to the end of the URL. The same concept applies for PDF output.
Select a row below to view the PNG output of the original visual. Go to Tableau Public to view any of the original visualizations, all of which are interactive.
