Minimal R/Shiny Interface to JavaScript Library ECharts • echarty

This package is a thin R wrapper around Javascript library ECharts.
One major command(ec.init) uses R lists to support the ECharts API.
Benefit from ECharts full functionality and build interactive charts in R and Shiny with minimal overhead.

Wider connectivity and deployment potential through WebR and crosstalk.
