This is a function definition. The function is used in the next step. It seems that the function transforms Polygons between two different formats. ESRI seems to be a company and probably this is some kind of proprietary data format for polygins (just guessing here).

It would be better you find some small dataset to experiment with, maybe a subset of your data. With that you could create a MWE ([Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757)) and from this I could help with real VegaLite code.
