mwrepjson ( python ) wrepjson ( magjson/magml )
For the needs of ecCharts and the epsgraph module, Magics can load input data formatted in a specific WrepJSon format.
In future releases, Magics will accept more generic format.
Restriction
As mentioned, the format was designed for the epgram products only. For efficiency, Magics relies on perfectly formatted data.

Eps format needed for Wave Plotting
//The wave distribution is done using the eight main directions:[east, nord, nord_east, nord_west, south, south_east, south_west, west]
// Each direction is itself split into 6 categories according the significant wave height, For example, for east, we have
// [east_one, east_two, east_three, east_four, east_five, east_six]
// each octant is coloured based on the distribution of significant wave height associated with each mean wave direction
