• echarts_from_json to create an echarts4r object from JSON options.

Arguments containing . have been replaced by _ for clarity. I.e.: coord.system => coord_system.

Deprecated functions from 0.1.2 have been removed, they can be found in the echarts4r.assets package:

• e_convert_texture
• e_stars_texture
• e_composite_texture
• e_globe_texture
• e_map_texture

The scatter family of function has been reworked: the scale argument now takes a scaling function. To accomodate to this, the e_visual_map function also takes, optionally, a scaling function.
Retired e_keras_history due to its uselessness.
