In dreamRs/topogRam: Create Interactive Continuous Cartogram

Description

Continuous area cartograms with d3.js and cartogram-chart.

Usage

topogram(
  sfobj,
  value,
  label = "{value}",
  palette = "viridis",
  rescale_to = c(1, 1000),
  n_iteration = 10,
  projection = "geoMercator",
  layerId = NULL,
  width = NULL,
  height = NULL,
  elementId = NULL
)

Arguments

sfobj	An sf object. For the time being, shape must be projected in Mercator (CRS 4326).
value	Variable name to use to distort topology.
