Standards nerd and technology enthusiast, Terence Eden, has published a South Up, Aotearoa Centred, Equal-Earth Projection Map [shkspr.mobi] which has the south end up and uses the Equal Earth projection to ensure proportional land-mass size. In other words, the globe has been rotated to 150° and created in a multi-stage process mostly using R. The borders are from Natural Earth, the country names from OpenStreetMap, and flags from Twemoji.
Country Names
Natural Earth only provides country names in English ☹ - but it also provides 2 character ISO codes. So I grabbed the country codes and names from OpenStreetMap [openstreetmap.org] and merged them into the data set using R.
The Code
This produces the country borders and names onto an SVG.
Manual placement
I used Boxy [boxy-svg.com] to edit the SVG and place all names in roughly the right place.
Conversion
Inkscape was used to open the resultant SVG at 72dpi. I then used Gimp to autocrop, canvas expanded to 16000x9000, and saved as an uncompressed PNG.
The Emoji wouldn't import to either Gimp or Inkscape. So I viewed the file in Firefox and then printed it to a PDF. That PDF was cropped using pdfcrop` [ctan.org] and then imported to Gimp.
