Clinton vs. Trump: The Battle for the Presidency


It’s election time, so time for an election viz. You will notice this is very similar to the RealClearPolitics version the difference being that I am calculating the 2-week average of all polls in their data set.

This little project also provided me a chance to try out the new Google Sheets connector in Tableau 10 and allow the extract to refresh on Tableau Public. In addition, I learned how to scrape a table from the web in a Google Sheet via this blog post, which should (if I did it right) update automatically.

This was also another chance for me to test out the Device Designer that came with Tableau 10. Enjoy!
