Circle

Takes a Point and calculates the circle polygon given a radius in degrees, radians, miles, or kilometers; and steps for precision.

Example

import json
from geojson import Feature, Point
from turfpy.transformation import circle

center = Feature(geometry=Point((19.0760, 72.8777)))
cc = circle(center, radius=5, steps=10)
print(json.dumps(cc, indent=2, sort_keys=True))
