All spend analysers that I've seen are the pie charts. But pie chart is not the best way to show a hierarchy of spending, because it is hard to compare spendings with each other in one category and across categories. This is another way to show how and on what we spend.
Check the live version. It's better in Chrome. At this moment it can parse csv files only from Discover bank. Maybe I will add some other file formats and banks in the future.
