Vvidget Server™ is used in custom web applications to make graphs like those shown below.

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.
• 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.
