    A data visualization and analytics component, especially well-suited for large and/or streaming datasets.

    As far as customizing the Perspective datagrid, the story on this is evolving :) . With the 1.0 release, we've released an NFT demo with a more current version of the plugin API, as well as new plugin API docs. Replacing innerHTML is only costly if you trigger a relayout before the replacement, which you'd want to avoid - check the pudgy-penguins demo source for examples which replaces these with without the intermediate DOM tree being rendered (though this is brower-dependent). If you can't, e.g. the replacement is async or whatever, the underlying regular-table component has an API that allows you to return the DOM elements themselves per cell, but you'd need to write a simple plugin to integrate this as Perspective's version provides its own dataListener.
