Insights in 5-D! (Using magic small-multiples layouts)
summary
Layout of small multiples changes what patterns are visible: a computed grid that maps facets to coordinates reveals spatial and demographic structure that alphabetical grids hide. The talk introduces the R package facet warp, which uses macro_x/macro_y numeric columns (longitude, latitude, population density, median age) and a 1987 snapping algorithm to place panels so counties or transit stops form mini-maps. Examples include all California counties and Chicago L stops; the package is released and works on arbitrary numeric layouts.
