If your privacy needs are fairly lax, I would go with Google Charts. They are free and pretty easy to work with. Just create an empty <div> and then have the Google Javascript load the image/interactive chart into that div.
http://code.google.com/apis/charttools/ <http://code.google.com/apis/charttools/>They offer static images and more feature-rich interactive charts that rely on SVG for their graphical drawing. Some really nice ones (like the Google stock/finance charts with advanced range options) utilize Flash, but most of the simples ones are SVG only :) Not sure about the performance of a hundred charts on one page, but Google's chart api is pretty snappy. Dan's charts are pretty cool too.
