Node Red Dashboard w/ LED
I found the github repo: https://github.com/node-red/node-red-dashboard
- Write admin tools from day one

[task] Program uplot support into node-red-dashboard (javascript)
The existing node red chart tools is not great. I'd like to be able to use uplot instead. The uplot-charts node should work very much like that charts node built into node-red-dashboard.
uPlot
- Small and fast 2D canvas chart for time series, lines, areas and bars

Rendering data that changes very frequently
Here is a very efficient 2D canvas lib that is extremely efficient https://github.com/leeoniya/uPlot i recommend looking through their readme and seeing if it solves your current problems.

BACKEND:
It's about 3000 lines of Crystal code https://crystal-lang.org/ -- it's been an absolute dream to program in. Ruby-like syntax, statically compiled performance. Nice standard library. Would recommend :)
Performance == caching
Local ephemeral filesystem for shortest-term caching.
Redis for shared medium-term caching and locking.
S3-compatible object storage for longest-term caching (for raw data feeds pulled every evening by a cronjob).

Bootstrap

Just a sprinkle of inline JS+CSS on the page.

It's always been you, Canvas2D
you can use matchMedia to detect devicePixelRatio changes and re-sync:

everything stays crisp even as you browser-zoom. e.g. https://leeoniya.github.io/uPlot/demos/area-fill.html

AMP Has Irreparably Damaged Publishers’ Trust in Google-Led Initiatives
Safari's slow release cadence (typically tied to OS version upgrades) does leave it more broken and for longer than Firefox, Chrome, Opera and other browsers that are updated more frequently and not tied to the OS.
just recently i ran into incompatibilities with Safari < 14 needing the old-spec matchmedia api:

JS library for graphing huge amounts of data
uPlot will handle this. https://github.com/leeoniya/uPlot

WebGL charting libraries
If you are showing 100s of thousands of points, I'd still go with canvas eg uPlot. It's a really, really excellent library.

Optimizing at the CPU instruction level in the browser w. Rust and WebAssembly
super cool!
i've done my share of optimizations and benchmarking charting libs [1] but this goes deeper still.
SVG is not a good choice for large raw datasets when you need performance.
