Javascript-based Charts

Today I'm trying to find out how to convert XML/SWF Charts into Javascript-based charts. First of all, I would like to explain why I'm looking for the information. As many of us know, XML/SWF charts can not be presented in mobile browsers. So, there is a problem.  I went out on Internet hoping to find something suitable for conversion.  Searching and searching, I found out a several possibilities for future mobile optimization.

• http://www.flotcharts.org/
• http://www.fusioncharts.com/goodies/fusioncharts-free/
• http://www.jqchart.com/jquery/chart/chartdata/xmlfile

The fourth one I like a lot because the data is driven from XML file, which is closed to what I need. I hope, my selection will work for conversion
