It mosaics an ImageCollection into a single image. The function can be called synchronously or asynchronously using an optional callback. It accepts visualization parameters (`visParams`) and returns a MapId or an object containing the map ID and token, which can be used with `ee.data.getTileUrl` or `ui.Map.addLayer`. The return will be `undefined` if a callback is specified.\n"]]
