A collection of hetero or homogeneous glyph renderers which represent a subset of data. The purpose of the composite glyph is to abstract away the details of constructing glyphs, based on the details of a subset of data, from the grouping operations that a generalized builders must implement. In general, the Builder operates at the full column oriented data source level, segmenting and assigning attributes from a large selection, while the composite glyphs will typically be passed an array-like structures with one or more singular attributes to apply. Another way to explain the concept is that the Builder operates as the groupby, as in pandas, while the CompositeGlyph operates as the function used in the apply. What is the responsibility of the Composite Glyph? - Produce GlyphRenderers - Apply any aggregations - Tag the GlyphRenderers with the group label - Apply transforms due to chart operations - Note: Operations require implementation of special methods tdefaulttNonethelpsIdentifies the subset of data.sU Array-like values, which are used as the input to the composite glyph. Most composite glyphs add their own representation of one or more values-like columns/arrays that they receive as inputs. These are compiled together for generating `source`, `data`, and `df` by the individual composite glyphs. s—The data source used for the contained glyph renderers.
