The issue occurs in the following scenario:
- The user pans the map to the East, resulting in the map data containing points for the East World map
- Then, the user pans the map to the West. When replicating points for the West World map, the process should not include the points for the East World map. Subtracting 360 from the East World map points will incorrectly map them to the central region. Thus, duplicating the points on the center map.
| westWorldFeatures.features.forEach(element => { | ||
| if (element.geometry) { | ||
| element.geometry.coordinates[0] -= 360; | ||
| } | ||
| }); | ||
| // netjsonGraph.utils.appendData call the render method which | ||
| // super imposes the data on the existing points on the map. | ||
| netjsonGraph.leaflet.geoJSON.removeFrom(netjsonGraph.leaflet); |

The points were getting duplicated by just using appendData. I reviewed the code of netjsongraph.js and appendData do not call netjsonGraph.leaflet.geoJSON.removeFrom(netjsonGraph.leaflet); like overrideData does.
I may be wrong, but we may need to replicate this in appendData as well.

I did not understand what you mean exactly with:

You mean that we should patch that method in netjsongraph.js, or what?
