Hi Anders,
I'm the developer of Leaflet.TimeDimension.
What do you refer about displaying polygons?
You might use a geojson layer where the features have a time property. You have to add to the map this layer using L.TimeDimension.Layer.GeoJSON, which is prepared to filter the features of the geoJSON layer according to the current time (and according the duration parameter). But it was developed with linestrings in mind, in order to show partial trajectories.
I will fix this on the next version of the library.
Regards,
Biel
