How to add GeoJSON layer to a Google map?
I have created a Google Maps JavaScript API project, and have an API key. (This renders a polygon but does not seem to support the styling of a MultiLineString). (This example allows for addition of GeoJSON via Drag and Drop but I do not see how to save the map and data layer.) Sample GeoJSON MultiLineString from http://geojsonlint.com :
What does geojsonlayer do in ArcGIS for JavaScript?
Since: ArcGIS API for JavaScript 4.11 The GeoJSONLayer class is used to create a layer based on GeoJSON. GeoJSON is a format for encoding a variety of geographic data structures. The GeoJSON data must comply with the RFC 7946 specification which states that the coordinates are in SpatialReference.WGS84.
Can a geojsonlayer accept more than one schema?
Each GeoJSONLayer will only accept one schema of the properties. The fields property can be used to specify the desired fields for the layer. If fields is not defined, the schema used by the first feature will be used to deduce the fields schema for the layer. GeometryCollection is not supported.
Is the GeoJSON data in spatialreference WGS84?
The GeoJSON data must comply with the RFC 7946 specification which states that the coordinates are in SpatialReference.WGS84. Please see the table below for supported geometry objects from GeoJSON and their corresponding geometry types:
How to convert MultiLineString to LineString in OpenJUMP?
OpenJUMP can handle all sort of geometries on the same layer. You can see 4 points and on multilinestring here. Notice the symbol with two linestrings. Select the geometry and use the geometry conversion tool. All done. Notice the linestring symbol and WKT presentation of the converted geometry. OpenJUMP can save the result back to GeoJSON.

How to convert MultiLineString to LineString in QGIS?
In QGIS, go to Properties -> Styles, add another line style on top of your current one, and change it to Marker Style. Then set it to last vertex only, and change the shape of it from a ball to a sideways triangle. With this, you know the start and end of each individual line in your multiline feature.
