Here are a few examples of visualization I've created in Tableau. These can be found along with all other examples at my Tableau Public profile.

This is a proof of concept dashboard for a fake company called "Faux Supply Corporation." I created the logo and utilized a company-specific color scheme. This is based on the Tableau Superstore data set and I did a little bit of simple exploratory data analysis (EDA) in Python which can be seen here.
