Additionally it should support files other than .csv, as per the upcoming spreadsheet compatibility changes.

I've incorporated the code into sortable_tables in v11, bar: proper documentation, renaming the addon, proper JS-framework-friendly templates.

I've tidied the addon up, and done some better documentation.
I haven't built a UI for assembling all the graphing blocks. There's examples for them all, and I don't think reading the code for these very simple blocks is asking too much given the huge leg up and relatively advanced nature of having graphing on your website. We can always improve things further in the future.

This is great. Thank you team and, of course, the client who requested this.
