Multigraph is software for creating 2-dimensional scientific data graphs in web pages. It can read data in a variety of formats, and allows you to customize the appearance of the graph to your liking. Multigraph provides interactive "pan" and "zoom" capabilities, giving the viewer the ability to change the horizontal and/or vertical scales in the graph on the fly. Multigraph also has the ability to read data from a web service, which allows it to be used to "surf" through large datasets, downloading only those the parts of the data that are needed for display.
Multigraph is an Adobe Flash application. It will work in any browser that supports Flash, which includes all major browsers. You do not need to know anything about Flash in order to create graphs with Multigraph, however. Multigraph uses a simple XML syntax to describe its graphs; to create a graph, you simply create an XML file.
