Shameful plug here - and yes dc.js is great!
An alternative web-component based approach to dc.js is available here: https://github.com/PolymerEl/multi-verse.
It is still based on Polymer 2.0, migration to lit-element in the way.
I recall seeing your project almost 2 years ago. A bit of unsolicited advice - It would really help if your Github and docs page linked to a few actual interactive examples showcasing the different chart types supported, and the general capabilities of your library. Screenshots really don't do justice to projects like dc.js and your lib that hinge on interactions between users and charts/data.
It also appears that your demo for multi-chart is:
1. Broken
2. Blocked by most browsers and requires manual override of security suggestions (probably related to https and some sort of cross-domain things going on).
I'd be curious to see any working examples like the one dc.js has on it's main doc page. Cheers
Thanks a lot for your advice! Live demo used to be working on webcomponents.org - one service powering them has stopped working...
I launched this approx 2 years ago - using it in prod, but not had proper time to devote on better doc/demo/presentation. Looking forward to it during current migration to lit-element.
