Live chart in the buffer

[Tom]

I store some data text files and the other day I though it would
be nice to have a rendered chart of this data right in the
buffer.

So I created this little toy package and I'm posting it here, so it
may give ideas to somebody to create a minor mode which, when
turned on, similarly as iimage-mode does with image links shows
rendered charts of tabular data in the buffer.

This package does not need any external tool, only an internet
connection. Just eval the buffer, see what happens and then start
modifying the table data.

Here it is. (Click on Raw to get the raw text file.)
