<strong>When creating choropleth maps, mapmakers often bin (i.e., group, classify) quantitative data values into groups</strong> to help show that certain areas fall within a similar range of values. For instance, a mapmaker may divide counties into groups of high, middle, and low life expectancy (measured in years). It is well known that different binning methods (e.g., natural breaks, quantile) yield different groupings, meaning the same data can be presented differently depending on how it is divided into bins.

<strong>To help guide a wide variety of users, we present an open source, web-based, geospatial visualization tool, Exploropleth,</strong> that lets users interact with a catalog of established data binning methods, and subsequently compare, customize, and export custom maps. This tool advances the state of the art by providing multiple binning methods in one view and supporting administrative unit reclassification on-the-fly.

<strong>We interviewed 16 cartographers and geographic information systems (GIS) experts from 13 government organizations, NGOs, and federal agencies</strong> who identified opportunities to integrate Exploropleth into their existing mapmaking workflow, and found that the tool has potential to educate students as well as mapmakers with varying levels of experience. Exploropleth is open-source and publicly available.

If you are teaching a course on choropleth mapmaking (data binning/classification, how they can sometimes be misleading), we provide a set of guided questions and exercises using Exploropleth to help students explore related concepts.
