Could I create a better documentation of the functions and objects of this lib?

While using the lib to create charts at my project, im being confused many times, because many params on documentation are just set as 'any'. 
If you create a more detailed documentation it can help us to better understand the functions, objects and implementations. You can just get the docs at https://echarts.apache.org/en/api.html#echarts put into an file and upload to the lib.
