This package helps you convert h3 hec code directly to geojson and a GeoJSON entity to h3 hex code.
Sample:
H3 to GeoJSON:
from h3converter import h3converter
h3converter.h3_to_geojson(['89be455030bffff','89be455030cffff'])
GeoJSON to H3:
from h3converter import h3converter
h3converter.polyfill({'type':'Polygon','coordinates':[[[144.244589, -36.810689], [144.244246, -36.808741], [144.241989, -36.807999], [144.240075, -36.809205], [144.240418, -36.811153], [144.242676, -36.811895], [144.244589, -36.810689]]]},9)
where polyfill has (geojson, precision).
