Review

The TL;DR;

The idea

Two types of thematic map for complex multivariate data

Elements in a tiled pattern ‘pick up’ data from area units to allow combining multiple choropleths in a single map

`weavingspace`

A python module available at github.com/DOSull/weavingspace

Install it with

> pip install weavingspace

Maps with just three lines of code!

tile_unit = TileUnit(tiling_type = "laves", code = "4.8.8",
                     crs = ak.crs, spacing = 500)

tiling = Tiling(tile_unit, ak)

fig = (tiling.get_tiled_map(prioritise_tiles = True)
  .render(ids_to_map = ids, vars_to_map = vars, colors_to_use = cmaps,
          legend = False, figsize = (10, 7)))
