Multigraph

Multigraph is a program 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 written in pure JavaScript and will work in any reasonably modern web browser, including on mobile devices.
