dataviz Presidential Elections Sankey United States Usa
How States Have Shifted Over the Past Decades
It's been a while since I've seen my first flow diagram. I always wanted to create one, using the Sigmoid Function, to try something new. I never had the right idea. But this week I thought to represent how states have shifted over the last decades and Us elections.

I looked for the data I needed and I created the dataviz below. It was an hard work, also because it needed several Calculated Field, for curves, colors and other. 

This is my tall Sankey diagram. The size of every state is related to his electoral votes. The coloured lines represent the states that have shifted between two consecutive elections. 

Here it is. Enjoy!
