I may be the only one that thinks this is cool, but I just have created a flash-based pie chart with Ming via PHP. Here it is in action:
I did this to integrate with an intranet application I built at work, but mostly it was excuse to try to actually create a Flash animation with the tools I have at hand, which are pretty rudimentary. In fact, as a pie chart outside of this application, it's kind of strange. There's no way to tell what the slices represent without moving the mouse over them, and there's no title to the chart (the example above is the number of pictures on my website from each year). For my purposes, this is fine, since the intranet application supplies all this.
But doing that was surprising difficult, mostly because I found little-to-no documentation about how to use Ming in PHP. There are some examples, but nothing very comprehensive. Not knowing how the Flash model works, I had a very hard time understanding the difference between a shape, display item, sprite, button, and so on, and when you can (or should) do what to which one. Even now, I haven't been able to figure out how to ensure each new slice's label appears on top instantly (if you look closely, in some cases it fades from the previous label).
