Data from Brazil states (and generic region) using VegaDatasets

Dear all, I have the following code that draws the US map with its states:

using VegaLite, VegaDatasets

# load JSON file containing map of US

us10m = dataset("us-10m")

# 1. US Map by State

# how to generate plot

p = @vlplot(
    width = 640,
    height = 360,
    title = "US Map by State",
    projection = {type = :albersUsa},
    data = {
        values = us10m,
        format = {
            type = :topojson,
            feature = :states
        }
    },
    mark = {
        type = :geoshape,
        fill = :lightgray,
        stroke = :white
    }
)

works perfectly.
How can I adapte this code to produce:

  1. the map of Brazil with its states.
  2. the map of the Europe with its capitals
  3. a general region, with a given points (Lat., Long) and conect some them. Is it possible to download the data from a url and insert this information in Julia?

I would like for these informations. Many thanks forr the attention.

The most up-to-date data for Brazil is maintained by IPEA, in the geobr dataset. We wrapped this dataset in GeoArtifacts.jl under the GeoBR submodule. You can use the package to download the data.

The data comes as geopackage files if I remember correctly. There are several packages in Julia to load the file. GeoArtifacts.jl itself will load the data for you, but you can use other lower-level packages as well. After the data is loaded, it should be easy to provide the information VegaLite.jl needs.

Please, could you insert the commands to imports these data? And to Europe, for example? I need only GeoArtifacts.jl?
I am an new user.
Thank you so much.

The commands are in the README of the package. For Europe there are other datasets in the package like NaturalEarth and GADM.
