I like the new 'Add Data' Widget in AGOL-WAB, but it wants to open from http: (URL). All I have is AGOL, desktop, and WAB site I created. I have a .csv file with a field called 'ZIP' and I have a feature class that has over 33,000 zip code centroids. What I would like to do, is load the .csv into the WAB site and have the zip code centroids appear as a symbol. I don't have a LAT/LON, just City, State, and Zip. No address. the .csv file changes daily as well. Any ideas are welcome. I know geoprocessing can work, I just cannot afford ArcGIS server. thank you
