As answered by people managing CheckIO and ZingGrid.
ZingGrid's answer:
Standard web platform using vanilla JavaScript and relying on the web components API so it is agnostic to framework use.
ZingGrid's answer:
We had built ZingChart, which is used by numerous small and large organizations worldwide, and wanted to address the other aspects of data presentation outside of charting. Given our emphasis at the time of long lived software we opted to go close to web platform and that is why we implemented it as a web component so early.
ZingGrid's answer:
Web standards-focused, framework agnostic, very easy to tie it to a REST or GraphQL endpoint, lots of hooks for customization, and very easy to get started with
ZingGrid's answer:
