Screenshot of one trial of the study, showing a pair of box plots with the question "How surprising would it be if samples A and B were from the same source?" 4 answer buttons are: not/slightly/quite/very surprising.

Screenshot of last page of a completed study with a summary of the participants responses and how they aligned with expectations.

I've updated my pairs study from initial feedback (thanks!): new question framing, rebalanced effects, phone-friendlier and now showing your results at the end. Testing round 2 now open: give it a try at xangregg.github.io/pairstudy121... #dataviz

I've been truly inspired by the archival work and writings on historical dataviz by @infowetrust.com, @attilabatorfy.bsky.social and @datavisfriendly.bsky.social. My main motivation here was to see if I can find #dataviz for the Indian context. This is a small start and part of the learning process!

Portraits of Population An archive of 700 hand-drawn charts and graphics from India's census, and why they were made

If you'd like to skip the story and just play with all the graphics and #dataviz, that's okay too! Here's a link directly to the explorer diagramchasing.fun/2026/portrai...

As part of population education, the government mandated that middle and high school students learn about reading charts and statistics and understanding terms like dependency ratio, mortality rates and other such concepts. We end up seeing such interesting takes on #dataviz as a result!

The Census of India has never been very reader-friendly. But in 1970s, a series of events led to government putting effort into publishing very interesting, truly "Indian" #dataviz for the average reader. My new story, with an explorer and some comics! More ⬇️

What are your go-to resources for scientific visualization? Do you have a favorite chart type that everyone else seems to hate? (I’m looking at you, pie charts... 🥧)

#Bioinformatics #OpenScience #DataViz #ScientificCommunication [5/5]

The lifelong craft of scientific visualization

In data-driven R&D, your model only matters if your stakeholders can understand it. 📉
Communicating insights is perhaps the only part of the process that truly "counts" at the decision-making level.

But great #DataViz is harder than it looks.🧵 [1/5]
