How to create a visualization

You will find 5 different visualizations in U.S. Political Stats, including: maps, bar charts, stacked bar charts, line charts and pie charts. Because the data varies with each type of data, not all visualizations are available for each of the data types. But viewing the data in multiple ways is a powerful tool to building arguments in your research.

  1. Maps
  2. Maps are available at the state, district and county level for Campaign Finances, Demographics, Elections, Floor Votes, Interest Group Scores and Voting Scores. To create a map visit any of these hubs of data, and go to the Select section. Click on Office, and select Senate for a national map with states.

  3. Bar Charts
  4. Bar charts in U.S. Political Stats give an aggregate view of the averages for a particular category. You can get to a bar chart by selecting Office and an Office on the Campaign Finances, Demographics, Economic Data, Interest Group Scores, Presidential Performance and Voting Scores pages.

  5. Stacked Bar Charts
  6. Stacked bar charts allow you to see how the division of data has changed over time. You can view this division on the Elections page in U.S. Political Stats, where you can see the change in the number of total votes in addition to the total number of Democrat and Republican votes.

  7. Line Charts
  8. Line charts are simple views of data over time. You can find these in each of the data topics. You can compare people, locations or branches.

  9. Pie Charts
  10. Pie charts are unique to Biographical Data and Supreme Court Cases, and can be compared to view how different the bigger picture looks.

How to Compare Data

Data is comparable on each of the data pages by clicking on the compare tab. Compares are set up to view as much applicable data as possible, but you will need to know what makes sense given the context of the government. For example, a comparison of Democrats and Republicans can provide valuable insights, but a comparison of Democrats from Rhode Island and Republicans from Oregon may not yield much valuable information.
