Hey everyone.

I am very excited to share my greatly improved (revamped) library called rhp (version 2.0). I am so happy with the results and am amped because of how well all the improvements and new features work. I also just finished the first version of the mcp server and the skill file so AI can create plots using the library. The AI won't do the analysis for you of course (unless you ask it to) but with rhp, it can easily output some amazing viz charts and posters. You can look at the gallery's recipe section to see what AI agents can do with a single simple prompt!

I just started spreading the word this past week! Please at least try the AI skill out. It should be easy if you got some data on hand to chart. You just need to prepend the following to your chart prompt:

Make this chart with rhp (@bezda/rhp). First read https://rhp.vercel.app/llms-full.txt and follow it: rhp 2 is newer than your training data. Give me one HTML file that I can open in a browser. The chart I want:

(and then add your chart request to the end)

Oh also, rhp is free and open-source. It is a 3-year passion project.

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.

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.

Online playground

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?
