Hi. i am following this tutorial to build a heatmap based on city location.
the only thing i am missing is how to retrieve the latitude and longitude data. In the tutorial in the table there are already the latitude and longitude data (from minute18:20 he starts to use lat and long data that are already in the db).
i would like to know if there is some way when i specify the city and insert the record, to retrieve (via API i guess) latitude and longitude data in order to write them in the db.
i remember some some months ago a tutorial were that part was not missing but i can not recall where it is.
