import time
from livemap.client import Map

# Setup a connection to the map server
map = Map("http://127.0.0.1:5689")

# Create an empty line
my_line = map.polyline("myline", [])

# Extend the line with new coordinates over time
for p in gps_data:
    my_line.extend(p)
    time.sleep(2)

You can change the color of the line: map.polyline("myline", [], color='red')

Load a geojson file

When the server is running, use the cli to load a file

livemap load-file mydata.json

This assumes the server is running at http://127.0.0.1:5689, but you can override it

livemap load-file -h 127.0.0.1 -p 5555 mydata.json

You can change the color of the line

livemap load-file mydata.json --color red

This is a sample geojson file that works with the load-file command:

        ]
      }
    }
