Trellis Views
A trellis view is a kind of graph view that displays a grid of multiple graphs, one in each data cell.
A trellis view falls into one of two subtypes:
Simple Trellis. A simple trellis displays a core inner graph multiplied across row sets and column sets, rendering many small multiples that are ideal for comparing and contrasting.
Advanced Trellis. An advanced trellis displays a grid of small spark graphs that are ideal for monitoring trends and spotting patterns in a data set.
