The Zoom attribute is to define the default zoom level of the map when it's loaded.
The Bearing is the compass direction that is 'up'. For example, a bearing of 90° orients the map so that east is up.
The Pitch attribute is to define the default pitch, in degrees. Zero is perpendicular to the surface, for a look straight down at the map, while a greater value like 60 looks ahead towards the horizon.

These values default to zero.

labels, icons and circles can also be aligned according to how the map is pitched by using text-pitch-alignment, icon-pitch-alignment and circle-pitch-alignment respectively.
The value given to text-pitch-alignment and icon-pitch-alignment attributes should be 'map' or 'viewport' or 'auto', and would default to 'auto'. If 'map' is chosen, the icon will be aligned to the plane of the map. If 'viewport' is cosen, the icon will be aligned to the plane of the viewport.
The value assigned to circle-pitch-alignment can only be either 'map' or 'viewport' and would default to 'map'. In this case 'map' means the circles are scaled according to their apparent distance to the camera and 'viewport' means that the circles are not scaled \`\`\`JS var map = new mapboxgl.Map({ container: 'map', style: 'mapbox://styles/mapbox/light-v9', center: [147.208298, -33.840466], zoom: 6, bearing: 10, pitch: 90 }); \`\`\` ` 39:[] 31:{"id":"83db3905d5276ae5","slug":"mapbox-gl-style-spec","title":"Mapbox GL Style spec","thumbnail":"efdd00ad0252c2c23baafcec7d8cf33b2b0fac343839186ebd36c5a32c86f98f","access_level":"public","create_time":"$D2018-08-15T00:45:06.862Z","update_time":"$D2018-08-16T07:40:10.160Z","view_time":null,"first_public_time":"$D2018-08-15T04:05:27.316Z","has_unpublished_edits":null,"fork":false,"stars":6,"starred":false,"owner":{"type":"team","id":"d17280eea747ce66","login":"thivya-ea","name":"","avatar_url":"https://avatars-next.observableusercontent.com/987cd4174fa4e908d2428f8d15a70480a7b1575d4497b2e019e3e35861e83ebb","tier":"starter_2024"},"version":393,"publish_version":393,"role":null,"authored":false,"authors":[{"type":"individual","id":"7b0636c5ea180bee","login":"thivya-ea","name":"","avatar_url":"https://avatars-next.observableusercontent.com/987cd4174fa4e908d2428f8d15a70480a7b1575d4497b2e019e3e35861e83ebb","tier":null}],"members":[{"type":"individual","id":"7b0636c5ea180bee","login":"thivya-ea","name":"","avatar_url":"https://avatars-next.observableusercontent.com/987cd4174fa4e908d2428f8d15a70480a7b1575d4497b2e019e3e35861e83ebb","tier":null,"role":"editor"}],"comments":[],"custom_thumbnail":false,"trashed":false,"lapsed":null,"subscribed":null,"forks":3,"collection":null,"type":"notebook","body":{"title":"Mapbox GL Style spec","cells":[{"id":0,"value":"md`# Mapbox GL Style spec`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":349,"value":"$33","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":15,"value":"polygon_fills=md`## Polygon fills`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":19,"value":"polygon_fills_solid_colour=md`### Polygon fills - Solid colour`","pinned":false,"hidden":false,"mode":"ojs","author":"$undefined","summary":"$undefined","output":"$undefined","database":"$undefined"},{"id":22,"value":"md`Filling the polygons with solid colours can be achieved by the fill-color tag in the 'paint' property.\n
