I'd like to embed network information in a web-page in a similar way that STRING does this, with movable and clickable nodes.

I am looking specifically for network.pl or a similar example. https://string-db.org/cgi/network.pl?taskId=IPrOTea9dOF3 Looking into the html code, STRING generates embedded SVG images in perl which contain the following code comment:

Generated using the Perl SVG Module V2.64
by Ronan Oger
Info: http://www.roitsystems.com/

And makes nodes movable using <script type='text/javascript' src='/javascript/svgmousemove_7025.js'></script>

There is no mention of the Perl code or license on the web page.
