I'm making an infographic on Bitcoin. How can I download all Bitcoin transactions to do some analysis? I would like to do some analysis of Bitcoin transactions in the last 3 months and share my insights by preparing an infographic. What would be the best way to get all Bitcoin transactions in the past 3 months?
A key element of the Bitcoin protocol is the block chain, which is a public transaction database. This contains most all transactions made in bitcoins and also includes information such as the sending and receiving addresses. You can find historical transaction data for the past 3 months by using a block chain explorer like ABE or Blockchain.info.

I would recommend ABE, only because it is written in Python, which will make it a lot easier to interface with for data analysis purposes.
