any static method
A client for accessing a GeoJSON
feature collection from any source
;
The source function returns a future that fetches data from a file, a web resource or other sources. Contents must be GeoJSON compliant data.
When format
is not given, then GeoJSON
with default settings is used
as a default. Note that currently only GeoJSON is supported, but it's
possible to inject another format implementation (or with custom
configuration) to the default one.
Use crs
to give hints (like axis order, and whether x and y must
be swapped when read in) about coordinate reference system in text input.

crs: crs,
