Makes every ECharts chart under a root accessible, including the ones drawn
after this is called.
For a page that holds charts it did not create itself -- a Superset or
Metabase dashboard, where each tile creates its own. Each chart is found by
the attribute ECharts writes on the element it was initialised on, and
bound with bindEChart; one that is disposed or removed from the
page is unbound.
