Sets the longitude coordinates (in degrees East).

Sets the latitude coordinates (in degrees North).

Sets the coordinates via location IDs or names. Coordinates correspond to the centroid of each location given. See `locationmode` for more info.

Determines the set of locations used to match entries in `locations` to regions on the map. Values *ISO-3*, *USA-states*, *country names* correspond to features on the base map and value *geojson-id* corresponds to features from a custom GeoJSON linked to the `geojson` attribute.

Sets optional GeoJSON data associated with this trace. If not given, the features on the base map are used when `locations` is set. It can be set as a valid GeoJSON object or as a URL string. Note that we only accept GeoJSONs of type *FeatureCollection* or *Feature* with geometries of type *Polygon* or *MultiPolygon*.

Sets the key in GeoJSON features which is used as id to match the items included in the `locations` array. Only has an effect when `geojson` is set. Support nested property, for example *properties.name*.

Sets text elements associated with each (lon,lat) pair or item in `locations`. If a single string, the same string appears over all the data points. If an array of string, the items are mapped in order to the this trace's (lon,lat) or `locations` coordinates. If trace `hoverinfo` contains a *text* flag and *hovertext* is not set, these elements will be seen in the hover labels.

Template string used for rendering the information text that appear on points. Note that this will override `textinfo`. Variables are inserted using %{variable}, for example "y: %{y}". Numbers are formatted using d3-format's syntax %{variable:d3-format}, for example "Price: %{y:$.2f}". https://github.com/d3/d3-3.x-api-reference/blob/master/Formatting.md#d3_format for details on the formatting syntax. Dates are formatted using d3-time-format's syntax %{variable|d3-time-format}, for example "Day: %{2019-01-01|%A}". https://github.com/d3/d3-time-format#locale_format for details on the date formatting syntax. Every attributes that can be specified per-point (the ones that are `arrayOk: true`) are available. variables `lat`, `lon`, `location` and `text`.
