aisdb.web_interface.visualize(tracks, domain=None, visualearth=False, open_browser=True)

Display tracks using the web interface.

To customize the color of each vessel track, set the ‘color’ value to a color string or RGB value string:

>>> def color_tracks(tracks):
...     for track in tracks:
...         track['color'] = 'red' or 'rgb(255,0,0)'
...         yield track
...
>>> tracks = [
...     {'mmsi': 204242000, 'lon': [-8.931666], 'lat':[41.45], 'time': [1625176725]},
...     {'mmsi': 204814000, 'lon': [-25.668333], 'lat': [37.736668], 'time': [1625147353]},
... ]
>>> tracks_colored = color_tracks(tracks)
