I would like to suggest moving ECharts document project [1] under Apache orgnization. Here are some of other projects under Apache [2]. This can help community better contribute documents.
Please vote for this. If it passes, I will open a JIRA ticket. [1] https://github.com/ecomfe/echarts-doc [2] https://github.com/apache?utf8=%E2%9C%93&q=doc&type=&language= Wenli
