      "source": "# One region at a time, across continents\n\nUse a matching subdivision map enabled native Aner development runtime and notebook integration. Aner Plot awaits a binary release; development runtime and extension packages are not distributed by the website.\n\nEach chart cell works on its own after the import cell. Install only its named `.anermap` pack, for example `aner maps install /media/maps/region.usa.co.anermap`. Importing `aner.plot` loads no geometry. A single region chart does not require a country, continent, world or neighboring region pack. Running every cell intentionally constructs seven separate charts and retains the selected scenes in notebook outputs.\n\nAll numerical values are synthetic teaching indices. Boulder is an illustrative latitude/longitude point over the Colorado state outline; this is not a city boundary, road map or surveyed observation. Lambert azimuthal equal area is a locally centered display projection; the source is generalized display geometry rather than an area measurement dataset.\n\nThe exact region IDs and join keys come from the published subdivision catalogue. Natural Earth source levels and vintages vary. Scotland uses the four country UK first order source; council areas remain explicitly described alternatives. Source attribution and licenses accompany output and optional packs.\n\nThe same analysis cells run as `.aner`, `.anernb` and Jupyter `.ipynb`. Existing notebook snapshots and supported HTML/SVG exports carry only their selected geometry for offline viewing. Rerunning code still needs the matching installed pack. No CSV, network service or map credentials are needed.\n"
