The 116th Congress will be seated today, so I wanted to use some data to show how the House was changed by the 2018 midterm elections. This visualization uses data I gathered from Wikipedia on January 2nd, 2019. I used Google Sheets to scrape the data and Tableau to visualize it. I plan to make more visualizations about congress using this dataset. You can follow us on Twitter see them as soon as they are ready.
If you want to keep up with our surveys and data analysis, be sure to follow us on Twitter and Facebook.
