Sandeep Shetty: @BarnabyWalters Very cool. What's the use-case though? Also is this coming of the doctrine based indexer that you had?

@sandeepshetty thanks! I’ve wanted to plot tag usage over time for a while now to see if there are any interesting patterns. I’m not using doctrine any more, in fact I’m not even using a SQL database for indexing until I really need one — data stored in yaml files, indexed by a csv file in ~210 lines of code — see also waterpigs.co.uk/notes/4TQNY2

When I post a note, adds one to the week counter for each tag, then I have an endpoint which makes that data into an SVG.
