Animate 3D buildings based on ambient sounds Disable map rotation Create a draggable Marker Create a draggable point Filter features within map view Filter symbols by text input Filter symbols by toggling a list Create a hover effect Display a non-interactive map Measure distances Get coordinates of the mouse pointer Highlight features containing similar data Select features around a clicked point Get features under the mouse pointer Restrict map panning to an area Create a time slider Toggle interactions Highlight features within a bounding box Fit to the bounds of a LineString Change a map's language

Animate map camera around a point Animate a point along a route Center the map on a clicked symbol Fit a map to a bounding box Slowly fly to a location Fly to a location Navigate the map with game-like controls Jump to a series of locations Play map locations as a slideshow Fly to a location based on scroll position Set pitch and bearing
