Hi team, I do have a Json array with many itens (id,lat,long)  
See example:  
msg.payload.users.messageList[1..n].message[1...n].latitude[0]  
msg.payload.users.messageList[1..n].message[1...n].longitude[0]  
msg.payload.users.messageList[1..n].message[1...n].id[0]

I was trying to consider the worldmap example but it uses a csv node to point itens on the map.

Does anybody has any example about how to point many itens in the map considering lat,long in a Json array ? Should I implement a loop in a function considering worldmap node?

The worldmap doesn't use csv - but it will accept an array of javascript objects like

```
[{"name":"thing1", "lat":51, "lon":-1}, {"name":"thing2", "lat":52, "lon":-2}, {"name":"thing3", "lat":53, "lon":-3}]

```

So you need to manipulate your array into san array like that.
