Sets the Layer or single View specifications to be layered.
Note: Specifications inside layer cannot use row and column channels as layering facet specifications is not allowed. Instead, use the facet operator and place a layer inside a facet.

Sets the angle value.
Sets the angle property.
Sets the overall size of the visualization. The total size of a Vega-Lite visualization may be determined by multiple factors: specified width, height, and padding values, as well as content such as axes, legends, and titles.
Sets the overall size of the visualization. The total size of a Vega-Lite visualization may be determined by multiple factors: specified width, height, and padding values, as well as content such as axes, legends, and titles.
Value parameters
- `type`
-
The sizing format type. One of "pad", "fit", "fit-x", "fit-y", or "none". See the autosize type documentation for descriptions of each.
- contains
-
Determines how size calculation should be performed, one of "content" or "padding". The default setting ("content") interprets the width and height settings as the data rectangle (plotting) dimensions, to which padding is then added. In contrast, the "padding" setting includes the padding within the view size calculations, such that the width and height settings indicate the total intended size of the view.
- resize
-
A boolean flag indicating if autosize layout should be re-calculated on every view update.

Value parameters
- format
-
Type of input data: "json", "csv", "tsv", "dsv". Default value: The default format type is determined by the extension of the file URL. If no extension is detected, "json" will be used by default.

Sets the top-level height properties to "container" to indicate that the height of the plot should be the same as its surrounding container. The width and height can be set independently, for example, you can have a responsive width and a fixed height by setting width to "container" and height to a number.

The width and height can be set independently, for example, you can have a responsive width and a fixed height by setting width to "container" and height to a number.
After setting width or height to "container", you need to ensure that the container's width or height is determined outside the plot. For example, the container can be a `
` element that has style width: 100%; height: 300px. When the container is not available or its size is not defined (e.g., in server-side rendering), the default width and height are config.view.continuousWidth and config.view.continuousHeight, respectively.

Sets the mark definition object. Marks are the basic visual building block of a visualization. They provide basic shapes whose properties (such as position, size, and color) can be used to visually encode data, either from a data field, or a constant value.

Sets geographic projection, which will be applied to shape path for "geoshape" marks and to latitude and "longitude" channels for other marks.
Sets geographic projection, which will be applied to shape path for "geoshape" marks and to latitude and "longitude" channels for other marks.
A cartographic projection maps longitude and latitude pairs to x, y coordinates. As with Vega, one can use projections in Vega-Lite to layout both geographic points (such as locations on a map) represented by longitude and latitude coordinates, or to project geographic regions (such as countries and states) represented using the GeoJSON format. Projections are specified at the unit specification level, alongside encoding. Geographic coordinate data can then be mapped to longitude and latitude channels (and longitude2 and latitude2 for ranged marks).

Selections are the basic building block in Vega-Lite's grammar of interaction. They map user input (e.g., mouse moves and clicks, touch presses, etc.) into data queries, which can subsequently be used to drive conditional encoding rules, filter data points, or determine scale domains.
Selections are the basic building block in Vega-Lite's grammar of interaction. They map user input (e.g., mouse moves and clicks, touch presses, etc.) into data queries, which can subsequently be used to drive conditional encoding rules, filter data points, or determine scale domains.
The simplest definition of selection consists of a name and a type. The selection type determines the default events that trigger a selection and the resultant data query.
Vega-Lite currently supports three selection types:
- "single" to select a single discrete data value on click.
- "multi" to select multiple discrete data value; the first value is selected on click and additional values toggled on shift-click.
- "interval" to select a continuous range of data values on drag.
Value parameters
- selections
-

When both types of transforms are specified, the view-level transforms are executed first based on the order in the array. Then the inline transforms are executed in this order: bin, timeUnit, aggregate, sort, and stack.
