javascript-charts-performance-com VS perspective

Thanks for the great summary. It's been years since I was in this field so very helpful to hear what's now available.

What would you use to plot (or downsample and plot) data that updates every second or more frequently? E.g. IoT data streaming in?

I used dygraphs (I think) a decade ago and recently found Lightning JS and this comparison [1] to other libraries, but the LightningJS license costs are prohibitive outside of well-to-do project domains. And I don't have data that updates that fast - just don't want it badly sampled or drawn.

Why do you want to render to canvas?

Perspective seems to be the most performant html table. It is more focused on extremely fast updates than styling, although it looks good.

Glide is a newcomer that also renders to canvas.

SQL workbench also uses https://perspective.finos.org/ for tables. It's a WASM table library which pairs nicely with duckdb and works well with large tables.

Yes. We are working on adding support for aggregation and pivoting using https://github.com/finos/perspective

I haven't looked extensively at react-datasheet. It looks like it is trying to build more of a full product than the other data tables.

I have used ag-grid extensively, its an impressive product. Some pieces are a little awkward to use, particularly auto-sizing. But generally ag-grid has thought of most functionality and has a solution. The creator of ag-grid had a great interview on Javascript Jabber [1].

The other serious data table component that I have seen is FinOS Perspective [2]. This is extremely high performance, also more specialized and probably harder to customize. I think Perspective renders to a canvas element from Rust/C++ compiled to WASM (not 100% sure). It is also made for streaming updates.

AG-Grid supports streaming updates... but only in the commercial version.

Eventually the data model for these types of tables becomes tricky. I will be investigating parquet-wasm for my use case. Hit me up if you want to collaborate.

Something like https://github.com/finos/perspective ? We use an OLAP(-y) WASM engine to provide query-ability to our data visualization tool, and doing the calculations in the browser is cheaper and simpler than a server-side database for datasets that fit in browser memory.
