Consider running the PPT through Keynote. There's lots of good export options.
I just created a
Flash-based project, very like your scenario (with JPG images out of Keynote). I used the Animation codec as my output (with a high keyframe interval, as there was only occasionally a new slide), and encoded to On2/VP6 (Flash 8). Files were small, and they looked good. SlideShowPro is the Flash playback environment.
Note the project referenced here was output at 320x240 to keep it small. I could have gone to 640x480 and it would have looked sharper, but it's less about data/charts.
Look at Camtasia's or some of Adobe's products for capturing demos or presentations - they do very efficient and elegant compression/conversion to Flash for web-based presentation.
