This is the evolution of the words “black rainstorm” on Twitter, following yesterday’s black rainstorm alert given by the Hong Kong Observatory, something that occurs a handful of times per typhoon season. I got the data from the Twitter Search API, parsed it with a Python script and made a graph using Google Chart API.

It was done in a hurry, but I will try to generalize this method (for future events) when I have the time to do it.
