Vvidget Server is used in web applications to make, i.e.: serve you up, graphs like that shown below. It is the first SOA (Service Oriented Architecture) server on the Internet.
Graphs are made from the key-value dictionaries described in this manual. The way to form the dictionary depends on your application. The list below gives some starting points.
If you are programming a ...
- Web interface then the Dictionary section gives examples of forming URLs in addition to describing the input forms.
- Web forms interface then the Forms section shows how to construct HTML FORM blocks for data input. With careful consideration, you can integrate forms with other technology to traverse data visualization with little additional programming.
- Web Application Server (ASP, WebObjects, PHP, etc.) then you need to form URLs using those facilities to make a chart. That represents a level of indirection because you are forming URLs, not images. That way of working is not immediately obvious so it is mentioned explicitly here.
- The Peer Visual Server is also programmable, but that use is out of the context of the Vvidget Server product. For additional information please contact VVI.
