The graphs below are produced by JavaScript, so all the data are sent to your browser for rendering. If your connection or computer is slow, these graphs will not be very useful to you; otherwise, they are fairly interactive. Google's Chrome browser is probably the best for this, but you will probably need more recent versions of any browser.
