Refactoring namespace #45
Description
The library at its infancy didn't have a clear scope but as it is used the needs are becoming more apparent.
Practically there are a number of conventions regarding the data that can be merged to just two:
- Source data, which includes: data(), _data, _raw
- Chart data, which includes: _raw, models, axis(), _axis
The different naming conventions can be merged which may result to a more logical schema.
