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-format/tree/v1.4.5#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/tree/v2.2.3#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 `a`, `b` and `text`.

Plots a scatter trace on either the first carpet axis or the carpet axis with a matching `carpet` attribute.

Sets the area to fill with a solid color. Use with `fillcolor` if not *none*. *toself* connects the endpoints of the trace (or each segment of the trace if it has gaps) into a closed shape.

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 hover 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. To be seen, trace `hoverinfo` must contain a *text* flag.

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

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.
