Windows only: Free application Tableau Public creates beautiful visualizations from your data and lets you publish them to the web, where users can interact with your charts and graphs with live updates.
The video above provides a great overview of how the tool works. Essentially, you import your data into the desktop Windows application, then play around with different charts, graphs, or other options until you find the visualization or visualizations that best fit your data. When you're happy with what you've put together, you can save the outcome to the web, which uploads the charts to the Tableau Public servers. From there you can embed it on any web page YouTube-style), and users can drill down into the data to their heart's content.
Here's an example of Tableau Public in action from a post on the Wall Street Journal:

Tableau Public is a free download for Windows, and looks like a great tool to try out next time you're looking to make your otherwise boring data come to life. Update: Somehow I managed to miss the fact that Tableau Public is only free on a trial basis; its actual price tag is extremely hefty. (Though if you're a student you can get it for as little as $69.)
Double Update: Actually, looks like Tableau Public is free after all! Straight from the horse's mouth:
"People can download the free tool and publish their visualizations of their data for free. Tableau Public includes a free desktop product that you can download and use to publish interactive data visualizations to the web. The Tableau Public desktop saves work to the Tableau Public web servers – nothing is saved locally on your computer. All data saved to Tableau Public will be accessible by everyone on the internet, so be sure to work only with [publicly] available (and appropriate) data.
When people want to analyze their private or confidential data (particularly data in data warehouses and other large databases), then they may want to consider our commercial products."
