What is Ranked Choice Voting?
RCV elections are just like a standard "first-past-the-post" election, except you can have backup choices. If your top pick has no chance of winning, you'll still have a say: your vote will count for your next choice.

Types of Visualizations
Bar Charts
The interactive bar chart shows how each round of the election progresses. The number of votes each candidate receives is represented by the size of the bar. As you progress between rounds, the bars grow and shrink to show the change in number of votes that each candidate is receiving.
The colors represent how many votes were gained in each round: for example, the yellow part of the bar shows the votes that were received in the first round.
The colors are perceptually linear, making them colorblind-friendly for all forms of colorblindness, including monochromacy (completely colorblind).
Sankey Diagrams
The sankey diagram shows how the votes flow from one candidate to another as each round progresses. This visualization is best for displaying how the eventual winner received their votes. By exploring where the votes flowed from, you can see candidates who were similar and those who were not.
In this example, you can see that Strawberry and Blackberry were most similar, and when Strawberry was eliminated, most of its votes went to Blackberry. That makes sense, given they are both berries. A real-world example might have a certain political party in place of berries.
Round-by-Round
There are several tabular formats, allowing you to inspect precisely what happened based on what you care about. The tabular-by-round format allows you to inspect the state of votes on a specific round. The tabular-by-candidate format (not shown here) allows you to dive into the number of votes a certain candidate had on each round.
Single Table Summary
The single table summary is a quick, noninteractive view that combines both the tabular-by-round and the tabular-by-candidate views. It gives a quick, at-a-glance summary of each round.
This table can also be exported to Wikipedia with several Wikicode features, including sorting each round by who had the most votes in that round, and including both percentage of votes and number of votes.
While all interactive formats have a noninteractive, print-friendly version, this single table summary is particularly well-suited for print where graphics may be expensive.

- "Blue Check" Verification: We'd like a system for displaying when a visualization hosted on RCVis has been vetted by an election administrator.
- User Dashboard: We'd like to provide users a method for managing their own visualizations, including modifying them, deleting them, and marking them as private.
