You can insert the Pivot Chart into a report as a Subreport.
(Just drag and drop the object from the database window into the detail section of the Report)
Then make sure in the properties of this new subreport, you set the "Default View" to "Pivot Chart"
<is it straightforwrd to automate these onto a Word document?>
No.
Exporting the Pivot Chart directly will result in a rather odd looking "table" in Word
Exporting the Access Report will not process the Pivot Chart Subreport, so irt will not appear in Word at all.
