Chess Metrics - monitoring personal progress

Although Chessbase (Light) and similar products allow to generate a bar chart on the number of games played by a player per year, of course a geek is not satisfied by that. A true geek wants to be in full control of his own data, so I wrote my own script that generates similar graph, but with breakdown per month. It's sad to see my activity in standard time control tournaments to go down so much after 2001, but on the bright side - I was instead learning scripting for all those years, so now I can delight myself with a chart like this one :)
