Dundas charts is a popular charting tool that embeds pie,
bar, line, and more charts into a web or windows applicatin. For the web,
Dundas generates the charts on the server and serves up images to the client in
the browser. This works well in the web environment, which relies upon the use
of images being present (whereas the windows realm can display an image
stream). Microsoft leased part of the Dundas controls to create the .NET chart
control freely available to the community, making all these great innovations
created by Dundas available to the public. Microsoft did not lease the entire
product, but rather a subset of the product.
