I use SAS On demand Academics for learning SAS. It has lots of other SAS software as a part of it. Do we have something similar for Tableau where no installation/ download needed to work on data sets?
Within Tableau Server / Tableau Online functionality exists to edit existing workbooks which have already been uploaded - Web Authoring in Tableau Server | Tableau Software
Generally speaking, the creation of reports in Tableau is possible only using an installed desktop / public version of the product, there is no equivalent version which is web only.
