Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Apache Arrow 3.0.0 Release
Not sure I follow, that page indicates that JS support is pretty good for all but the more obscure features (e.g. decimals) and doesn't mention data visualization at all? Anyhow, I've successfully used https://github.com/vega/vega-loader-arrow for in-browser plots before, and Observable has a fair few notebooks showing how to use the JS API (e.g. https://observablehq.com/@theneuralbit/introduction-to-apach...)

Show HN: Matrices – explore, visualize, and share large datasets
Hey HN, I'm excited to share a new side project I've been working on.
The product is called Matrices. You can check it out here: https://matrices.com/.
With Matrices, you can *explore*, *visualize*, and *share* large (100k rows) datasets–all without code. Filter data down to just what you want, visualize it with built-in charts, and share your results with one click.
You can use it today (no login or waitlist or anything). Just copy and paste your data from a google sheet or CSV file.
It's hard to describe the feeling of "gliding over data" you get with Matrices, so I'd rather *show* you how it works instead. This 75s video will give you a sense of how it works: https://www.youtube.com/watch?v=Rrh9_I3Ux8E.
Data is stored locally in your browser until you publish it, though small sample does go to the OpenAI APIs for AI-assisted features.
I started building Matrices because I wanted a tool that made it easy to explore new datasets. When I'm first trying to dig into data, I'll have one question... that leads to another... that will invariably lead to five more questions. It's sort of a fractal process, and I couldn't find many good options that were fast, responsive, and visual.
I figured this crowd would be interested in tech stack as well, it's using arquero [1] bindings over apache arrow for in-memory analytics, and visx [2] for visualizations. I'd like to add duckdb-wasm support at some point to open up a wider set of databases. Data is serialized as parquet to save a bit on bandwidth + storage.
Give it a spin, and let me know what you think. This is my first 'serious frontend project' so I appreciate any and all feedback and bug reports. Feel free to comment here (I'll be around most of the day), or shoot me a note: [email protected]

Hal9: Data Science with JavaScript
Transformations: We found out that JavaScript in combination with D3.js has a pretty decent set of data transformation functions; however, it comes nowhere near to Pandas or dplyr. We found out about Tidy.js quite early, loved it, and adopted it. The combination of Tidy.js and D3.js and Plot.js is absolutely amazing for visualizations and data wrangling with small datasets, say 10-100K rows. We were very happy with this for a while; however, once you move away from visualizations into real-world data analysis, we found out 100K rows restrictive, which gets worse when having 100 or 1K columns. So we switched gears and started using Arquero.js, which happens to be columnar and enabled us to process +1M rows in the browser, descent size for real-world data analysis.

Apache Arrow 3.0.0 Release
Take a look at the arquero library from a research group at University of Washington (the same group that D3 came out of). https://github.com/uwdata/arquero
What are some alternatives?
perspective - A data visualization and analytics component, especially well-suited for large and/or streaming datasets.
