Multigraph is a software system that allows you to create 2-dimensional scientific data graphs in web pages. It allows you to customize the appearance of the graph to your liking very easily, and can plot data from a variety of formats. Multigraph graphs are interactive --- they allow the user to change the scale(s) on the horizontal and/or vertical axes 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.
A graph is created in Multigraph by writing an XML file that describes the details of the graph, including which axes to draw, how to label them, where to find the data to be plotted, and the styles and colors to be used in plotting the data. No programming is required; to publish a web page containing a Multigraph graph, you simply create the XML file describing the graph, and an HTML file that invokes Multigrah with that XML file, and place both of these files on a web server.
Multigraph uses the Adobe Flash browser plugin, which is supported (and usually installed) in almost all desktop web browsers. In particular, it works in Firefox, Internet Explorer, and Safari. Knowledge of Flash programming is not required for creating or using Multigraph graphs, however.
For those who are programmers, though, Multigraph is also available as an Adobe Flex library component, so that it may be used in other Flex applications.
