cyclone symbol for matplotlib (clockwise & anticlockwise, filled & hull)
Raw
cyclone_symbol.py
"""Cyclone symbol. Includes anticlockwise (for northern hemisphere) and
clockwise (for southern hemisphere), filled and hull variants.
The path data is derived from 'weather-icons' repository on Github. Link:
https://github.com/erikflowers/weather-icons/blob/master/svg/wi-hurricane.svg
With slight modification, the path in this file is almost identical to the
icon in the SVG file.
