How to view/ingest data with VegaLite?

Hi

I have a topojson file and a dataframe.
Using a DataFrame I can see a “table” with all my values. But how can I do that using VegaLite?

Most of the given examples in the documentation have examples with the Vega datasets. But I have my own dataset in my computer. So, how can I view/ingest my data?

For example in this website: https://www.flirtwithjulia.com/2019/02/18/Choropleth-Map-With-VegaLite.jl.html
this is used to ingest a Vegadataset.

How can I do that if my dataset is in my computer? In a path like this: /home/julius/roc/topo/topojson.log

I believe this answer also addresses this issue, right?

Yes. This is the link: https://discourse.julialang.org/t/how-to-make-vegalite-read-my-topojson-file/34546/10
