You do not seem to have a topic yet. You are very passionate about using Tableau as a software package, but what is the topic you are interested in investigating. There are tons of research that has been done using Tableau. Examples of such include:

1. Using Tableau to decide description logics with full role negation and identity by Renate A. Schmidt and Dmitry Tishkovsky
2. Public Data and Visualizations: How are Many Eyes and Tableau Public Used for Collaborative Analytics.
3. Coupling Tableau Algorithms for Expressive Description Logics with Completion-Based Saturation Procedures by Andreas Steigmiller, Birthe Glimm, and Thorsten Liebig

You must produce a topic in the form that I have shown you instead of merely saying that you will like to work with Tableau. You need to solve a problem using Tableau, which I think will be very exciting research to do. Once you do this, your topic will be approved
