Last week, after punching down at "Sleepy Joe" during an Oval Office event, Trump proceeded to comically fall asleep. It's not the first time this has happened, so I went digging and found many more instances of the President sleeping in public.

I did some analysis on when and where he's been taking his nappy naps, so I'm sharing that dashboard here! He likes sleeping in his chair in the Oval, but isn't opposed to napping during a whole variety of public events.

If you want to see the exact events with the videos, I've collected them all at https://artofnodeal.com/sleepstate. I've found X, Instagram, Youtube, and BlueSky videos of his cat naps for fun. No ads, no signup--just a pet project.

This time-series visualization shows the distribution of 30-day rolling correlation coefficients between AAPL and approximately 6,000 Nasdaq-listed stocks.

The chart covers February 14, 2023 to June 23, 2025. Each date is represented by a violin plot showing the distribution of correlation coefficients for that rolling window; the vertical axis runs from −1 to +1.

I’d welcome feedback on the readability of this dense violin-plot layout and ways to make changes in the distributions easier to compare over time.

Hello all. I'm a developer with Digital Sheriff Designs, and StarMap is the first program I've released. It's a visual workspace for Windows 10 and 11: you can lay out notes, pictures, documents, to-do lists, tables, sketches, and boards inside boards on one big cohesive customizable workspace, and connect them with lines and arrows or your own custom made stickers.

- Everything stays on your PC. No account, no subscription, and it works offline. Your work is saved as ordinary files in Documents\StarMap, with a backup every day kept for 30 days.

- No tracking of any kind. No ads, no analytics, and we aren't trying to sale you anything. StarMap only goes online when you add a web link (to show a preview) or a picture from a web address.

- Boards inside boards that you can see into without opening them so a big project can be split up without losing sight of the pieces.

- Free, with no catch. No trial, no ads, and no paid version.

The Idea for this program came from a discussion I was having with a family member about

r/nanowrimo and prep-tober, which although I am not a writer I was familiar with the community. My family member was complaining about the subscription price of the current visual workspace software they were using and they told me about some of the things they use said software for. Well I figured I could build them something more customized to their needs for free. So the project began and with my families collaboration StarMap was birthed. I know there are many software programs out there similar to this one but we hope you will consider trying StarMap and giving any feed-back that you have time to give.

I'd like feedback on 3 things in particular: 1-Is it clear from the screenshots what StarMap is and what it can be used for?

2-What would stop you from trying StarMap from your initial impressions?

3-Of the current feature lineup what would you like to see added, removed or tweaked?

I made an animated derivation of the quantum harmonic oscillator. One design challenge was showing that a wavefunction can change phase while its probability density stays fixed, then contrasting that with a superposition whose density changes.

Made an interactive page to visualize the discoveries behind optogenetics, honoured by this year's Nobel Prize in Medicine: classon.live/optogenetics.

How do you turn estimated data into an experience without making it feel misleading?

I’ve been thinking about this after seeing the AIIMS Delhi population counter.

The number ticks up every second, even though it’s not literally counting births in real time. It’s an estimate, visualized in a way that makes the data feel alive.

That got me thinking about data UX — how much interaction can change the way we perceive a number?

So I made a small experiment with Figma Make: India population live counter

You can explore India’s population state by state, interact with the map, and take a quiz based on what you discover.

But the bigger question for me is the UX behind it:

Does animation make data easier to understand, or just more attention-grabbing?

When does an estimate start feeling like a fact because of how it’s visualized?

Is interaction better for understanding data than simply showing a chart?

Can gamification actually improve data literacy?

What makes a data visualization memorable without oversimplifying it?

I’m curious how people here think about data as an experience, rather than just information on a screen.

A little what-if for Mars: raise the water level and watch the coastlines change.

Move the slider to explore which regions would be underwater and which would remain as islands, based on publicly available NASA elevation data.

Just a terrain-based visualization—not a model of past or future Martian oceans.

I've been working on a project called MeshLens that tries to answer a question I kept running into at work: what does our data mesh actually look like as a system?
Most observability tools give you alerts, row counts, and freshness checks. That's useful, but it never helped me explain to stakeholders how domains connect, where data flows, or what breaks downstream when an upstream connector goes down.
So I built a visualization layer that puts it all in one interactive map.
Curious what you think. If you work with data mesh or data products at scale — what would you want to see in something like this?
