OK Lets get started with this and we can work out the others later.

How about we provide a menu item (provided via plugin) that says "Create
Chart"

If the user has a valid selection already (some numbers in CSV or tab
seperated form or a row or column from a table), the Chart Guru is spawned
with this data already loaded. The data used by the chart is the selection
from the document.

You could also have a menu item "Update Chart". If the user already has a
valid selection, you update the chart with the numbers in the selection.

Otherwise you pop up a dialog, "select numbers from your document".

User selects number from a table row, column, CSV list etc, then presses
"OK" data is inserted into the chart.

I can help you with the AbiWord part. It's not hard at all.

I agree with robsta that it would be great to just gnumeric as only means
of manipulating numbers, but we have to start somewhere. Users ARE able to
copy and paste gnumeric data into table is abiword so the connection is
not totally lost.

There are also plenty of "Stand Alone" use cases. Often people have tables
of data in their document that they wish to display graphically. In that
case it makes perfect sense to just use AbiWord.

I'm really looking forward to this :-)
