- 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.
- Graphing Libraries that are as good as Excel?

Show HN: Inflation-adjusted stock charts – Total Real Returns
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).
FRONTEND:
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.

[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.

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.

Streaming HTML out of order without JavaScript
There's a long-standing WHATWG feature request open for it here: https://github.com/whatwg/html/issues/2791
And several userland custom element implementation, like https://www.npmjs.com/package//html-include-element
One of the cool things that you can do with client-side includes and shadow DOM is render the included HTML into a shadow root that has s, so that the child content of the include element is slotted into a shell implemented by the included HTML.
This lets you do things like have the main page be the pre-page content and the included HTML be a heavily cached site-wide shell, and then another per-user include with personalized HTML - all cached appropriately.

Htmz – a low power tool for HTML
I think there's a pretty strong argument at this point for this kind of replacing DOM with a response behavior being part of the platform.
I think the first step would be an element that lets you load external content into the page declaratively. There's a spec issue open for this: https://github.com/whatwg/html/issues/2791
And my custom element implementation of the idea: https://www.npmjs.com/package/html-include-element
Then HTML could support these elements being targets of links.

I thought, oh, that's not so bad. Then I realized what I was looking at was a 10 page index.

Is Htmx Just Another JavaScript Framework?
I'd love to see something like HTMX get standardized, but I'm extremely pessimistic for HTMX's prospects for standardization in HTML.
In talking to a few standards folks about it, they've all said, "oh, yeah, you want declarative AJAX; people have tried and failed to get that standardized for years." Even just trying to get
to target a section of the page that isn't an has been argued about and hashed out for years.<p>Why is that? Well, for example, here's the form you have to fill out to start standardizing a front-end feature. <a href="https://github.com/whatwg/html/issues/new?assignees=&labels=addition%2Fproposal%2Cneeds+implementer+interest&projects=&template=1-new-feature.yml">https://github.com/whatwg/html/issues/new?assignees=&labels=...</a><p>It asks three main questions:<p>* What problem are you trying to solve? -
