If you are committed to a "codeless" solution, then Lotus 1-2-3 or Excel might be your best bet. (I guess Google Docs would be the closest thing to a "free" alternative to these proprietary tools.) Whatever you do, some customization will be required of you. If you use Lotus or Excel, you probably won't have to write code per se, but you will most definitely have to do some kind of mapping or configuration (e.g. using the GUI) to get the graphs looking how you want.
