The Juice Analytics Weblog, is chock full of good information, but a couple Excel visualization techniques have caught my eye recently. The in-cell graphing technique is quick and simple but can help one make sense of some types of data without creating a full on chart. This post got so much attention, that there is a follow up post that offers a few more techniques.

More recently, Chris challenged the readers to come up with some different ways to create square pie charts in Excel. The results are impressive! Two sample spreadsheets and a screencast are available to get things started.
