For today’s blog post, I decided to examine the voting data for presidential elections post-WII.
My first visualization lays out the number of votes for the Democratic and Republican candidate, as well as the total number of votes.
This allows us to see the trend in number of voters overall and for each party, as well as see which years the Democrats and Republicans won respectively.
My second visualization focuses on the vote difference between the winning and losing party.
The bars are highlighted with the party color of the winning party that year. Darker colors indicate that the party was the incumbent party. This visualization allows us to see that Republicans tend to win by higher margins than Democrats. Republicans also tend to win more when they are the incumbent party.


Nice job, Simhwee! Those are really good-looking graphs, with judicious choices of colors and labels. That annoying “Play” symbol is a problem with Tableau graphs; I’ll have to try and remember how we dealt with it last year.
Nice job on this post. I was a little bit confused by the “Play” buttons but after viewing the comment above, I can see that it is an error with the actual program that was used. It was really interesting to see the overall change in the political climate over the years, as one party would garner more votes than the other, and every so often they would switch off. This would be particularly useful in analysis of a party changing its political views over time.
