Subject: A game of Dota is so full of little interactions and variations that can be analyzed like: the position of the mouse on the screen at a given time or the keypresses along the game. So the purpose is to shed a light on how a specific role is played, or how a patch changes how the game is played.

The Data: I pretend to generate my own dataset, if not possible to use something like this I could use a dumped dataset (http://www-958.ibm.com/software/data/cognos/manyeyes/datasets/dota-2-winrates-percentages/versions/1.txt) or the tables from dotabuff(http://dotabuff.com/heroes/impact?date=patch_6.79)

Tools: Mostly graphic tools (illustrator and  photoshop) and to analyze the data Excel or processing.
