Well, for a correct sentence you would go for, "My Grandmother, God rest her soul, was the best cook and baker I knew."
I would think that comma would be the best punctuation. Hope this helps!
the reader would try to get information from the graph.
for example:
there has been alot of rain going in california. but how could we know if it has lessened or have grown more ?
<h2>a graph is just a tool to see progress. :)</h2>
i hope it helped
