RainMan is a automated rain graph generator. It collects current rain data from the internet and stores it in a database for later access. When a graph is requested, it takes the options selected by the user and reads the proper data out of the database. It formats and feeds this data, along with some of the selected options, to a program called gnuplot, which generates an HTML5 canvas element and draws the graph. This way, all graphs are automatically generated and they don't need to be stored on the server.
If you want to be able to generate additional statistics or record data for other locations, send me an email, and I'll consider adding it.
