# Accumulation charts for instant-runoff elections

## TL;DR

This paper introduces an 'accumulation chart', a new graphical method for visualizing instant-runoff election results that enhances clarity, shows vote transfers, and reveals candidate coalitions.

## Contribution

The paper presents a novel visualization tool that improves understanding of instant-runoff voting outcomes and vote dynamics compared to traditional charts.

## Key findings

- The accumulation chart clearly indicates the winner.
- It effectively depicts the instant-runoff process.
- It reveals candidate coalitions and vote pedigrees.

## Abstract

We propose a new graphical format for instant-runoff voting election results. We call this proposal an "accumulation chart." This model, a modification of standard bar charts, is easy to understand, clearly indicates the winner, depicts the instant-runoff algorithm, and summarizes the votes cast. Moreover, it includes the pedigree of each accumulated vote and gives a clear depiction of candidates' coalitions.
