We're not even using lit. Feel free to check out the code[0]. It's not the best (we're still learning web components) but it's working pretty well for us so far.

Thanks! I'll take a look

That's quite a commitment to write "naked" web components by hand.

Kudos on keeping external deps to an absolute minimum

They're not perfect. In particular accessibility probably isn't very good. But that hasn't been as high a priority since it's a dataviz app anyway.

It would be good to tell us, why you doubt the GP in that regard.

Because authoring web components is pain.

Because browser APIs and elements are quite limited so you're likely to pull in external deps tht provide better interfaces etc.
