@dee077 we need to add an example here to demonstrate the movement of node. I tried to come up with the following example:
netjsonmap-moving-node.json
{
"type": "NetworkGraph",
"label": "Moving Node Demo",
"protocol": "OLSR",
"version": "0.6.6.2",
"metric": "ETX",

"nodes": [
{
"id": "10.0.0.1",
"name": "India-1",
"location": {
"lng": 72.8777,
"lat": 19.076
},
"properties": {
"time": "2025-12-04T00:00:00.000Z"
}
}
],
