First I thought about categorizing all my myself, by copying and pasting the activity from my Chase account to a Google Spreadsheet.
That turned to be a hard and slow process. So I got a Mint account to help me with that. Though some spendings were categorized wrong, it definitely saved me a lot of time. After that, I exported the results to a .tsv file.
For the two sketches, each column is a day, and each rectangle a transaction. They are dimensioned according to the amount of money.
In the first sketch, each line represents a month. In the second one, all data is on the same visual level, and the vertical lines sign a month change.
