Twitter Sentiment Analysis

Does anyone have an end to end Twitter Sentiment Analysis offering? I'm struggling with the piecemeal and fragmented responses on the forum and in the documentation.
By way of example, is it possible to mine twitter on say "Australian Bushfires" and:
a) produce a plot of the number of tweets by day over the past month,
b) produce a sentiment analysis and word cloud,
c) list and map the location of users.
There are many easy to follow guides for R. I'd like to do this using rapidminer.

(c) is tricky as Twitter seems to be suppressing the geo-location fields from what I can see. See attached ExampleSet that I just did using "Australian Bushfires". If you have Twitter results with the geocoding, then it's just another visualization.
Note that the visualizations you ask for you are not done in a process but rather in the Results view. Word Clouds (for (b) )and line graphs (for (a) ) are done this way.
