Great, it is our pleasure to add you as the mentor.
The ECharts proposal on wiki.apache.org has been updated by John.D.Ament
to add you.

Yes, although there are many contributors, the active core developers now
are all from Baidu.
We want attract more developers to join this project, that is one reason
We want to become an apache project.
