It is worth making a separate note for Tableau Public, the free-to-use web-based, publicly accessible version of Tableau Desktop which enables you to create interactive visualisations and embed them into your website, publish them on the Tableau Public Gallery or share within the Tableau Public community. Note, the visualisations cannot be saved locally, that is the ‘public’ essence of this free tool, but you can now link up to 1 million records.
