Nice list! I remember HN talking about https://students.brown.edu/seeing-theory/ when it came out but sadly it seems like this website was discomissioned. Added an entry for my data visualisation tool here: https:&#x2

Amazing work! Reminded me of LLM Visualization ( https://bbycroft.net/llm ) except this is a lot easier to wrap my head around and that I can actually run the training loops, which makes sense given the simplicity of the orig

I ended up making my app installable as a PWA based on this conversation myself. Changes were straightfoward to add on top of a Vite + React application: https://github.com/visprex/visprex/pull/62/files

Yes as dimava commented above a PWA would be a great alternative. > in a way it can be more honest for a developer with any commercial intentions to not open source something while offering paid ways to modify the source code I appreciat

Great project! I'm also maintaining a fully in-browser data visualisation/analytics tool [1] and I often found it hard to convince people that their data isn't sent anywhere. It's funny I also say the exact same thing th

Very interesting read, I wish more startups did postmortems like this. It seems like the authors managed to build a set of tools that provided real value that ultimately did not make commercial sense, but would've been interesting to s

Nice visualisation! Some entities seem to have "undefined" on the graph that you might want to double check.

Yes now I'm looking at the tests I can see that the coverage won't increase linearly, but 12% (with some of the hard parts) in two weeks is impressive. I starred the repo, good luck with your journey :)

dayjs seems like exactly I was looking for, thanks for the suggestion! I might have tried to write a parser myself otherwise.

I will try to add more support for other data formats like xlsx and parquet in the future. Current CSV parsing is also a bit limited (i.e. cannot deal with timestamps) so I will try to update parsers first. Also thanks for the error checker

Thanks for commenting this, I would say speeding up the iteration between visualisation steps is the main benefit as you might not want to be thinking about matplotlib syntax when trying to get a sense of data distributions.

Thanks for trying it out! This is unfortunately not possible as of now and is one of th high-priority tasks to parse timestamps and datetimes, which is now incorrectly parsed as a string (Categorical). I'm using Papa Parse to load CSV

Aesthetically it looks like the game has come so far over the past 11 years but I was surprised to see that some rather advanced features like logisitic robots were already in this version of the game. Latest trailer: https://www
