Alpha release

As mentioned in the project proposal, the data we use is from this kaggle page, and all information we need is included. In alpha release, we are trying to make sure we can embed graphs in our project website, and to show we are able to make inference using existing data.
As an example, we show the total sales of each platform group (either Nintendo, Sony Entertainment, Microsoft Xbox or other consoles) across all years.

From the graph, it is clear that Sony and Nintendo are the two leading forces in the market, while Microsoft is not close to those two.
