Thinking about your specific request a little more - it would need an
additional field with the date that the book was read. The collection
has a field for when a book was added to the collection, which is how
the current graph is created. In order to track the number of books
read over time, which is what I think you're looking for, there would
need to be another date field. If I improve the graph to plot all the
date fields, that new custom field could be included.
