Thrilled to share Exploropleth - our new #GIS #dataviz tool. 💡 @Mapmakers, you can simultaneously explore & compare 16+ data binning methods on a choropleth map, directly in your browser! 🎓 @Instructors, you can use the tool to teach how choropleth maps can mislead people! exploropleth.github.io

Screenshot of a new, open source, web-based, geospatial visualization tool, Exploropleth, that lets users interact with a catalog of established data binning methods, and subsequently compare, customize, and export custom maps. The screenshot shows small multiples of 16 choropleth maps each showing Life Expectancy data for US counties, but using distinct data binning methods (e.g., natural breaks, standard deviation, pretty breaks, and so on).

New article! A fantastic new tool Exploropleth: exploratory analysis of data binning methods in choropleth maps, from @arpitnarechania.bsky.social Alex Endert & Clio Andris doi.org/10.1080/1523... #GISchat website exploropleth.github.io video of the tool in action: www.youtube.com/watch?v=lNV8...

Figure 5. Combine View lets users analyze a) a combination of one or more binning methods by visualizing b) the most consistent Bin, c) the frequency of the most consistent Bin, and d) both together for each U.S. county in separate choropleths. The new, resiliency binning method then utilizes this information to g) determine “resilient” bins (counts, intervals) that are also visualized in a choropleth. Hovering any county on the map shows a tooltip with relevant information about the county, as shown in e) and f).

Hi data people, check out Exploropleth! exploropleth.github.io/exploropleth/. It's free, open source software that shows how binning methods affect maps. There's also a teaching worksheet and a journal article in CaGIS: exploropleth.github.io @arpitnarechania.bsky.social & @alexendert.bsky.social

Different maps that show life expectancy by county in the U.S., where the data is divided using different data binning methods.

❓Do people’s perception & utilization of guidance change during analysis if they know its source, e.g., if it came from 🤖AI, 🧙Human Expert, or 🧑‍🤝‍🧑Group of Human Analysts? ✨Thrilled to share our new #iui2025 paper, presented last week at ACM IUI in Cagliari, Italy. (1/6)

Teaser figure showing our study prototype for visual data preparation and analysis, with a Data Attributes View on the left (showing the list of data attributes of an uploaded dataset), a Data Records View in the center (showing summary statistics and individual records for an attribute), and a Guidance Panel to request guidance (in the form of data attribute recommendations to shortlist) on the right.
