I would like to find a tool/plugin that enables charts/graphs to be
automatically created directly within Adobe InDesign.

In other words, while laying out an InDesign document, I would like to
be able to pull data into a chart that can be used directly in
InDesign, *not* simply importing a graphic of a chart already created
in another program.

If there is a program/plug-in that works with a dynamic data source,
attaches to XML stored in a fixed location, or simply allows a matrix
of data to be pasted in order to create the chart directly in
InDesign, this is precisely what I'm searching for.

Thank you in advance!
