Add a delimited file (CSV) to the map

This sample shows how to add a delimited file (CSV, TSV, PIPE) to the map by converting it into GeoJSON. The spatial io module analyizes the data and looks for common column names used to store latitude and longitude values. If no suitable column if found it then analyizes the data in the first row to seeif any column contains any strings in well known text (WKT) format.
