The encoding shelves are grouped into positional channels (e.g. x, y), mark channels (e.g. size, color, shape, detail, text), and facet channels (e.g. row, column).
To visualize data, you can drag-and-drop a data field onto an encoding channel shelf (e.g., x, y, color). By default, the system encodes raw (unaggregated) values. You can select a transformation such as an aggregation, binning, or time unit function via a pop-up function menu.
By default, the system automatically picks an appropriate mark type. You can override this choice using the mark selector drop-down menu.
The row and column channels can be used to create vertical facets and horizontal facets for trellis plots.
Quantitative fields have a function pop-up for specifying various aggregations and bin.
Temporal fields have a function pop-up for specifying various time-unit functions.
