Google Apps as a Mashup Environment – Slides from #guug11

FWIW, here are the slides from my presentation on “Mashing Up Google Apps” at the excellent Google Apps UK User Group (#guug11), as hosted by Martin Hamilton at Loughbourough University yesterday.

The “mashup environment” diagram was generated using a desktop version of Graphviz, but it can also be generated using the Google Chart Tools Graphviz chart, as in the example below:

Here’s the “source code” for that image:

digraph googApps {

CSV->URL
HTML->URL
XML->URL
event->GoogleAppsScript
GoogleAppsScript->"<GoogleMaps>"
GoogleAppsScript->GoogleMail
GoogleAppsScript->GoogleCalendar
GoogleAppsScript->GoogleSpreadsheet
GoogleSpreadsheet->GoogleAppsScript
GoogleAppsScript->GoogleDocs
GoogleSpreadsheet->JSON
email->GoogleMail
GoogleMail->email
GoogleDocs->GoogleAppsScript
GoogleCalendar->GoogleAppsScript
"<GoogleForm>"->event
event->GoogleSpreadsheet
time->event
"<GoogleForm>"->GoogleSpreadsheet
URL->GoogleSpreadsheet
GoogleSpreadsheet->"[GoogleVizDataAPI]"
"[GoogleVizDataAPI]"->"<GoogleVizDataCharts>"
GoogleSpreadsheet->"<GoogleGadgets>"
}

And finally, here’s a snapshot of the hashtag community around the event as of mid-morning yesterday:
