Charting the Beatles is the brain child of Michael Deal, a New York based graphic artist. In his words:
These visualizations are part of an extensive study of the music of the Beatles. Many of the diagrams and charts are based on secondary sources, including but not limited to sales statistics, biographies, recording session notes, sheet music, and raw audio readings
Eventually, Michael intends to produce a book of these charts, and has a placeholder website that should have more details once they’re available.
There’s also an extensive collection of pictures available on his Flickr group.
