Renders a Google Maps visualisation of lat/long coordinate data from the query.
MAP — set as ReportType in def_report.
def Render(self, Param1="", Param2="", Param3="") -> str:
The query must return rows with columns: latitude (col 0), longitude (col 1), label (col 2). The chart type is google.visualization.Map with tooltips enabled.
This report currently returns "Maps require an API key" unconditionally — the map rendering code is unreachable. A Google Maps API key must be configured and the early-return removed before this report will function.
