Hi there,
When I use [Vega's `flatten` transform](https://vega.github.io/vega/docs/transforms/flatten/) in Kibana 6.2.3, I get a message saying `Unrecognized transform type: "flatten"`. I assume the version of Vega used in Kibana does not support this transform yet. Is this correct?
If yes, is there a way to check the Vega version used in the current version of Kibana?
Thanks

@m.hashemian correct, the flatten transform [was introduced](https://github.com/vega/vega/issues/1155) in Vega 3.1, while Kibana 6.2 shipped with the earlier Vega version. To see which version is there, open a Vega visualization, open browser's debug console, and type `VEGA_DEBUG` - that object will have everything. Also, I have already updated the [Vega plugin](https://github.com/nyurik/kibana-vega-vis) to use the latest Vega & Vega-Lite, but there is currently no support for 6.2 yet, only 6.0 and 6.1. Hopefully I will update it to 6.2 soon.

Thanks, @nyuriks. I will wait for the next Kibana release (6.3) and try it again there. I assume Vega will also be updated with this release.
