Topic: Data processing and visualisation
This site is an online demo of a site which usually runs within a LAN for a group of researchers doing mass spectrometry.
Data files can be uploaded and are then processed automatically. The site heavily uses xajax (edit: not 0.6 but 0.5) , mostly to dynamically create/modify tables of data.
Also nice graphs are plotted using xajax and jpgraph.
Just click around.
