I have a website with a map that shows parcel data, you know...houses, buildings, land. I am looking for guidance on how to lasso a region of the map to select every parcel in the selected range.

My design approach to building this tool is to first get something working to be able to lasso a region and show the selected parcels in it. Step two is to figure out how to do the exporting of the selected parcels. I was informed at DS2019 to use sketch tool, but I need deeper documentation on it if that is true.
