JavaScript Diagram Builder - Introduction

The JavaScript Diagram Builder v. 3.3 is a library of some objects and functions, which can help you to display a coordinate diagram (resp. a chart or graph) in your webpage in an easy way. The file 'diagram.js' contains all the necessary objects and functions. This file must be included in the header of your webpage:

<SCRIPT Language="JavaScript" src="diagram.js"></SCRIPT>

The script will best work with Microsoft Internet Explorer 5.x, Netscape 6.x, Opera 7.x or Konqueror 3.x under Windows and Linux, but it will also work with Netscape 4.x and Opera 5.x under Windows and Linux with some restrictions.

The JavaScript Diagram Builder is especially useful, if you want to display a coordinate diagram (chart or graph) which depends on the client's input parameter or from data of a database.

The JavaScript Diagram Builder v. 3.3 is copyrighted freeware. It is provided "as is", without a warranty of any kind. If you encounter any bugs, or if you have any suggestions for further versions, then send me an email.
