RANKED CHOICE VOTING BALLOTS ARE EASY TO FILL OUT.






RCVIS MAKES THE RESULTS EASY TO UNDERSTAND, TOO.



Charts, graphs, and tables to help your audience understand the results of a
Ranked Choice Voting election. Export to Wikipedia, embed with HTML, or share to
social media.




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 gets the fewest votes, they are
eliminated and your vote is transferred to your next choice.

Learn more on our medium post: An Illustrated Guide to Ranked Choice Voting.




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.

FUTURE DEVELOPMENT

RCVis is free, open-source, and nonpartisan. These are our top projects. If
you'd like to help fund the development of RCVis, or volunteer your time as a
developer, please get in touch: team@rcvis.com.

 1. Accessibility: RCVis is not screenreader-friendly, though we have an
    undocumented audio captions for each visualization. We'd like to make these
    audio captions widely available, as well as making all RCVis visualizations
    screenreader-friendly.
 2. ES&S Data: We'd like to be able to upload and visualize data from Election
    Systems & Software voting machines.
 3. Infrastructure Updates: We'd like to use enable autoscaling to better
    support the influx of users and uploads on election night, as well as other
    infrastructure updates for stability and speed.
