Great perspective on how to think of social media as its own tech stack. Immediately rings true but had never thought of it in those terms.

I wonder if this technology could be used to train an emulator. For example, could you take the internal state of a Nintendo system and the image output as training data, and "teach" an emulator to run instread of coding those mappings explicitly? youtu.be/3UZzu4UQLcI

I used to fly Cessna 152s and this makes me more than a little nervous.
Taking a look at the #Spotify API and noticed a lot of interesting song features. Any great UI's out there for visualizing playlists?

New d3.js tutorial is up on chartfleau.com. Happy with how it looks, but hard to gauge if it's written at an appropriate level for the audience. Let me know if I can explain anything better.
New tutorial on making swarm plots with @d3js_org. chartfleau.com/tutorials/d3s… #dataviz
Really interesting 3d visualizations, I'd love to know how they're made.
Dancing Busses... Using the same daily bus totals from my previous #dataviz I have created a more abstract depiction of bus journeys in #NYC. Sorry about the compression! 4k hopefully coming soon... #3d #maps #animation #houdini
Going to write a tutorial on beeswarm plots in d3 this week.

I still expect very much to have to answer the "But what does a CVO... do?" in the same way I tried to answer that question about what a Senior Data Visualization Engineer does in this piece. medium.com/@Elijah_Meeks/wha…

I think more sites should be using Nivo for data visualization with #reactjs. Or are they already and I just haven't noticed?
Fascinating generative artwork.

In this column, @bariweiss does a great job analyzing the @joerogan-Spotify deal from the vantage point of legacy media. Highly recommended. [Full disclosure: I appear quoted here briefly.] nytimes.com/2020/05/25/opini…
