Cartogram in R not distorting countries as expected

由 蓝咒 提交于 2021-01-28 23:02:07
问题 I'm using the cartogram package in R to make a world map of living languages. The country map is from Natural Earth, and the language count from the Ethnologue. w <- readOGR('.','ne_110m_admin_0_map_units') L <- read.csv('languages.csv',sep='\t') w$rank <- 1:nrow(w) wl <- merge(w@data,L,by.x='ISO_A3',by.y='iso3',all.x=T) wl <- wl[order(wl$rank),] wl[is.na(wl$Live),'Live'] <- 1 w@data <- wl w2 <- cartogram_cont(w,'Live',prepare='none') plot(w2) The data I'm using has 111 living languages in

D3.js - Changes from path.area in version 2 to version 4

问题 I am trying to update d3-cartogram to work with D3.js version 4. So far, everything is going fine — I've just been updating all the functions so that they're written in the flattened namespace of version 4. For example, instead of d3.geo.path() , it's d3.geoPath() . I've also changed a few small things so that the code works with the latest version of TopoJSON. For example, instead of topojson.object(topology, geom).coordinates , it's topojson.feature(topology, geom).geometry.coordinates .

using cartogram.js for visualizing information in a global map

问题 I'm trying to adapt this example http://prag.ma/code/d3-cartogram/ to show information about obesity in 2002, 2005 and 2010 around the world. This the visualization: http://datauy.github.io/obesity-cartogram with a link to the code in the same page. The problem I'm trying to resolve is that the shapes are not being distorted like in the original example with the alberusa projection. The colors seems to be mapped just fine but for some reason I can't distort the map. I tried changing the scale

Use Rcartogram on a SpatialPolygonsDataFrame object

问题 I'm trying to do the same thing asked in this question, Cartogram + choropleth map in R, but starting from a SpatialPolygonsDataFrame and hoping to end up with the same type of object. I could save the object as a shapefile, use scapetoad, reopen it and convert back, but I'd rather have it all within R so that the procedure is fully reproducible, and so that I can code dozens of variations automatically. I've forked the Rcartogram code on github and added my efforts so far here. Essentially

Population-weighted polygon distortion (cartograms)

问题 I'm trying to create a map in R that conveys both the shape of underlying geometry (i.e., the physical boundaries) and the relative importance of the object in terms of an associated value. For concreteness, I'd like to focus on reproducing (a version of) the following map* (the shapes , not so much the colors since I can't find the polling data): I also don't want to bother with getting Alaska and Hawaii to appear below the US instead of in their geodesically correct locations. I'm only as
