Two-variable bivariate choropleth — bivariate_map • countryatlas

A 2-D bivariate choropleth with a built-in 2-D legend (via the optional biscale package), e.g. GDP per capita x life expectancy in one map.

Usage

bivariate_map(
  data,
  fill_x,
  fill_y,
  palette = "GrPink",
  dim = 3,
  projection = "equal_earth"
)

Arguments

data: An sf map-ready frame (use geometry = "sf").
fill_x, fill_y: The two value columns (unquoted).
palette: A biscale palette name (default "GrPink").
dim: Bivariate dimension (2 or 3, default 3).
projection: Projection.

Value

A ggplot object (the map; combine with biscale::bi_legend() for a standalone legend).

Examples

if (FALSE) { # \dontrun{
world_data(2020, c(gdp = "NY.GDP.PCAP.KD", life = "SP.DYN.LE00.IN"),
           geometry = "sf") |>
  bivariate_map(gdp, life)
} # }
